my diff does not have that mounting holes is there one that will mount to a '57 ford 9"?thanks for the pic.

 it's funny you guys bring up the damper or whatever it's called because I was talking yesterday with a buddy who builds hotrods and he brought up the same thing. I will look into that ,willing to try anything.i don't recall having the vibration with the c4 or when it was a 3.10 open but then again didn't put the car on the highway until the t5 was in it. 

a quick update.i've installed 4 degree wedges to get the correct pinion angle.i got a new tailshaft bushing and seal.I've installed the seal(holding off on the bushing for now).bought a new slip yoke and ujoints.took the driveshaft back to the company that made it last year to have it balanced they called and said it was bent and needed to be replaced.they went good for all but $50.i will install tonight and road test.when I installed the t5 last year I was trying it out and on a hard launch I got a lot of wheel hop for which the next weekend I installed traction masters,could this wheel hop have caused the driveshaft to warp?

is there a way to change a tailshaft bushing on a t5 with the tranny still in the car?since the t5 swap ive got a vibration and very noticeable at 70mph.let me back up its a 66 coupe ,289 with an 86 t5 in it,9" rear end.also I am getting a new slip  yoke as the old one is the origonal from the 6cyl c4.any recommendations?i've always had a minor drip out of the tailshaft seal..the ujoints are new as well as the driveshaft(which will be going back to be balanced.also the pinion angle is in question I have 2.5 deg down at tailshaft and 0 deg at pinion any recommendations on shims would be appreciated as well.thanks in advance. 

anybody know why when I installed a cheap grant steering wheel my power steering got jerky and not what I liked with the stock wheel?it's a borgeson unit that I've had for 2yrs and felt great with stock wheel but my 6'8" son complained he needed more room to shift the t5 upgrade so I thought a smaller wheel would help along with seat track extenders.but not happy any help would be appreciated.

hi julien i had the same problem with my installation on my 66 coupe.my rag joint actually ripped apart(luckily it happened in the body shop)borgeson replaced it with a ujoint and 2000 miles with no problems.the spring under the steering wheel is always pulling on the shaft.ms"s bearing in the column is the way to go as it will hold the shaft in place.borgeson is aware of this problem on the 64-66 kit.they sent out the ujoint at no cost.i didn't have to cut my shaft when installing the ujoint.

i have decided on jba 1650s or hedman 88408,maybe patriot hb8433.my questoin now is how important is primary tube size as the hedmans are 1 1/2" and the jba's are 1 5/8"

how is the sound with the hipos?

thanks guys,do you both have t5 with clutch cable set up?do the patriots hang low?going to shorties to stop melting clutch cable and sick of them hitting everywhere on these rough roads here in maine.

I KNOW THIS HAS BEEN BEAT TO DEATH BUT WHEN SEARCHING PAST POST I NEVER FOUND A DEFINATE ANSWER.i have a 1966 coupe 289(stockheads) t5 with ms cable,borgeson ps.i have long tube hedman on it now that need replacing and hang to low,going with shortys.is there a shorty that will bolt in without a bfh?i just want an easy installation without having to modify anything else(dont want stock or hipo) .looking at patriot clipsters or hedman elite.cost is facter but if there is one that will clear everything with no mods that cost more i will save a little longer for an easy installation.thanks in advance.

ms do you have them available now i will order them along with the cable clutch pedal assembly i will need for the t5 swap.also i've been reading that you like the motorsport progressive front coils,do you get the 620 1" lowering?i would like to do away with any spring spacers.

sorry to keep posting but the shocks are hooked up as i did the work and the tire rubbing was because the fender was down 1 1/2-2" on the tire
