Thanks Daze, I put one of your DIY kits on my car back in the early days of the roller perches along with your Arning drop template. One of the best mods I've ever done to my Mustang.
Best wishes on continuing success.

Got my Mustang in December 2004. Joined in 2005 when I installed the  MS power brake mod. Been here almost every day since.

I was 12 when my 66 was built, Bought it when I was 50...

Billy, check out AMK Products. They have bolt kits for everything on your car. The Mustang vendors have them.

I used their water pump bolt kit on my car, it comes with a chart showing where each bolt goes. 
Their stuff is often used for restorations because it is so exact. 

It's an 89 crown vic roller 5.0 block .030 over with flattop pistons. Iron gt40 heads, mustang gt 5.0 roller cam. Weiand street warrior intake and the summit 500 carb. Pertronix 3 in the factory  distributor. Starts easy and runs very well. Built it myself and it now has over 30k on it. I'm happy with it.

The car is like yours but I have a c4 automatic.

You might try to pressurize the cooling system with a loaner tool from your local parts store. Might make the leak more obvious.

And even then double check everything. I got a flexplate that was packaged wrong from Summit Racing when I built my 302. Shook like you would not believe. And get your rotating assembly balanced. I did not do that the first time and had to tear it all down and start over. 

Don't know if you figured this out but I think you have the black and green wires backwards. I looked at my Sun tach today and the black goes to the negative side of the coil and the green is the ground for the light.

Hope this helps...

 

Awesome, when was the last time you saw 3 '58 Impalas in the same place?

I am finishing up my project doing the same thing to my 66 Mustang. I am using  a 2010 Corolla column from a pick-n-pull. Mine works but the steering is stiff and has hardly no return to center. I have a factory power steering car. Still has the original box. Replaced all of the linkage with manual steer parts. Fun project but I am trying to solve the stiff steering. 

I drive mine a lot. I've had it 16 years and have put over 30k on it. It was down for 3 yrs when the engine let go. It's down now while I convert from hydraulic power steering to EPAS. I'm getting close to being done. Then I'm adding A/C. the climate in KC is such that I never park it for the winter. There's usually nice days here and there even during the winter when I can drive to work.
