BB - That's why I wanted to get both axles in with wheels on the ground before torquing the nut.

Cab4word67 - Nope, didn't miss

@Bentworker - Thanks, that's what I was hoping. Best case scenario for me. This is why I consider myself a life-long learner - another lesson learned.

It must have been around 2004 - 2005 for me. Maybe earlier, maybe later - I don't really remember.

I found this board when I was thinking about selling my '68 because it lacked all of the modern conveniences - power disc brakes, power steering, power windows, etc. A friend of mine at the time told me that all those things could be retrofitted if I wanted to spend the time to do it, so I started surfing the web and landed here. I haven't posted much, just absorbed the accumulated knowledge. I appreciate the true community feel of this board - I'm not aware of many other discussion boards that regularly meet in person. One day, I hope to join you all.

Thanks MS!

The greatest mistake was pressing the bearings on before verifying that the axles were right.  Over the years I've ended up with so much stuff that was wrong that I now take nothing for granted.  On axles I would check that the splines fit into the diff, that the bolt pattern was right, that the drum or disc fit the hub, etc., etc. before doing anything with them.

I don't think Yukon is saying the parts old on Amazon are not theirs.  I think they are saying that they are no responsible for how a third party listed their parts on Amazon, and frankly they're right.  However, if the info on their website and the Amazon site are exactly the same you may have a case, as it would appear the Amazon site just copied theirs. 

A final option would be to talk to your credit card company, assuming that's how you paid.  The only downside there is you don't want your method of payment blacklisted in the event they refund your money.
 

I agree completely. I take full responsibility for assuming this would be a simple "buy a set of axles for a X car" when I knew I was making a significant mod with an unknown housing. I think I'll just chalk this up to an expensive learning experience and move on. I'll put the Yukon axles up for sale on CL or fleabay until they sell and hopefully recover most of my money.

Here's the deal, this isn't just about the bolt pattern. Truck's that have a 5x5.5" bolt pattern also have a pretty big brake register and a larger brake offset. You can re-drill all day long, but if those other measurements are wrong the axles won't work. I recently ordered a set of Moser axles for my truck and had to take all those measurements so all that is fresh in my mind. Here's the Moser order form, what I would verify is A and B for sure. https://www.moserengineering.com/sites/www.moserengineering.com/files/New-Orderform-w4-link_1.pdf

Thanks for the link.

The biggest problem I have is that I don't have the axles that came out of my 9" housing, and to complicate things further, the housing has been shortened by 2" and I'm installing disc brakes from a Crown Vic.
I pulled the original 8" rear end and measured everything up as well as I could - here's a diagram of my measurements (full size image here):

 

I talked to Yukon and apparently their "Amazon store" has absolutely no affiliation with them, and since I had the bearings pressed on, they won't take the axles back. I'm going to get everything assembled on my bench as far as I can, take measurements and get back to them, and hope they can find something that will work for me, otherwise... I'm not sure what.

I think at this point, I'm going to go ahead and pull my original factory rear and put it on the bench right beside the new housing just to be sure there aren't any other fitment problems. The new 9" axle housing is from a '50s - '60s Ford something or other - it's the smooth round rear that all the hotrodders seem to like. If everything measures up good, I'll go ahead and install the 9" housing and diff this weekend. That will at least let me take measurements for the driveline, and will feel like I'm making progress, instead of what's becoming a big pain in the rear end (pun intended).

Thanks, I'll give them a call if I don't hear anything from the message I sent. Their Everett shop is about a four hour drive from where I live, so I could maybe make it a road trip and bring the family along to score a point with the wife.

What shop in Everett? Randy's Ring and Pinion? I'm about two miles from there.
 

That's the one. If I had my private pilot license I'd just fly up there as they're right next to Paine Field, I believe.

Well, I called all of my local machine shops and none of them wanted the job (too many problems with that sort of thing), so I guess I'm buying another set of axles. I messaged Yukon support about the problem last night, but haven't heard back from them yet. Incidentally, I bought these from Yukon's Amazon shop which made no mention of bolt patterns other than in the "Q&A" section at the bottom of the item description, where someone asked about that and was told that they are drilled for multiple patterns - must have been for a different product, I hate that about Amazon.

Anybody need a brand new set of axles? 

So I finally got my new Yukon 9" axles back after having a local shop press the bearings on, and when I mocked them up with my Crown Vic rear brakes for the first time, I realized that the bolt pattern is wrong... 5x5.5 instead of 5x4.5.

Someone please correct me if I'm wrong - I think the hubs can be re-drilled with the correct pattern, but I'm not sure if that's a DIY job, or if I should have a machinist do it. I have a benchtop drill press and I'm sure I can get the right drill bit, but I'm not a machinist and I don't want to screw up a brand new set of axles.

Thoughts?

That might have been mine at rosehillperformanceparts.com under the tech section.  Don't know if you have sourced parts, but I changing my setup and have those arm rest up for garage points.  LMK.

Thanks Glen, that was definitely your mod that I saw back then. I don't know how I missed that - I've had your site bookmarked since way back then.

When I first saw your article, I wasn't prioritizing interior parts because the Fox Mustangs were plentiful back then, and my build was a long way from worrying about anything on the interior. I got lucky a few weeks ago and found a set from a '93 convertible and grabbed them. They're not the right color, but I'm pretty sure I can paint/dye the hard parts and just buy new upper pads in the right color.

I thought about grabbing the mirrors as well, but they looked too chunky for my taste. Instead, I'm going to use a set of power mirrors from an early '80's RX-7 and wire them into the Fox mirror switch, based on a mod I found on another forum here.

Airplanes were my first obsession...

Mine too. I started down the road toward becoming a career pilot, but life happened and I ended up putting my training aside just short of earning my Private Pilot license back in 2005. I went back at it a couple of summers back, but found it too hard to schedule the trifecta - instructor, aircraft, and my own free time, all at the same time, but I'll get there eventually! I have my Student license, so I guess I technically qualify as a "certificated airman". Maybe.

What I would really like to see in a classic Mustang is a Merlin v12, like The Beast over in the UK; 1972 custom built around a Spitfire engine.
