Ok, I'm the one thats about to put the 351W and T5 in my 68 (you're probably getting tired of me by now). I found out that the late model autos and T5's are the same length as each other, I've also found out that early 3sp and 4sp manuals are the same length as each other. So if anyone has swapped an early manual for a late manual or auto, did you have to have your driveshaft shortened? Or lengthened? I'm thinking that I saw Horsepower TV put a tremec (same length as T5 also) into a 65 with a 4speed (originally) and didn't have to have it shortened which would mean my 3sp. and my T5 should be the same length, right? If I'm thinking right, I shouldn't have to have it shortened or lengthened....right????? Any thoughts or advice????

Can't you just use a tape measure and see if everything is the same, or at least very close. I did this when i swapped a different tranny into my s-10, and it worked fine.

The Horsepower TV episode you mentioned did have to change the driveshaft length. The trow it in there when they talk about needing to change the spline count too. But that show in peticular was full of mis-information...like when they say to fill the tranny with 3 quarts transmission fluid! What they should have said was GM syncromesh fluid. Also they should be castrated for butchering that car like they did! You will need to get the driveline length changed most places around here only charge 50.00 or less.

I've swapped from a 3 speed to a 4 speed toploader (same driveshaft) then a t-5 with the correct output yoke and had to shorten the shaft 3/4", then swaped to a c-4 and had to lengthen the shaft 3/4". So in my humble opinion with the correct output yoke you'll need to shorten your driveshaft 3/4" or so. This was on a '66 by the way.

Ready for a confusing sob story....when I put the T-5 in my coupe, being a dumb a$$, I shortened the original Hipo driveshaft by 5/8". Had a vibration after awhile. In the meantime I ordered an aluminum driveshaft for Becks 66 convert with a T-5 and 8" rear. Just out of curiosity I tried to put it in my coupe with the 9" rear, it worked, don't have as much free play as it should. Of course had to get another driveshaft for Beck car. But, whatever you do, get a T-5 yoke, even though the toploader will work, less vibrations.

And if you need a driveshaft custom built try Denny's driveshats. He does good work at very reasonable prices.

thanks guys!! I actually have a yoke, crossmember, and a few other things that i bought as a conversion kit from Dallas Mustang. The yoke is for a T5 that will also use stock size u-joints. What I have now is a 3speed toploader. But now I'm confused between BillGear and Steve66.

It depends on the length of your yoke and whether or not you have a 9" rear in the car. Also my experience was with a '66 so, after you get the tranny installed you'll see if it needs to be shortened or not. Good luck,

My 67 coupe came with a C-4 and 8 inch rear, 51 inch driveshaft measured center to center of u-joints.
Used the same shaft with the T-5 yoke when I swapped to the T-5, perfect fit.
The nine inch rear is 1 inch longer so the shaft will have to be shortened to 50 inches unless I use a short yoke on the rear end which is another option.
Hope this helps.

thanks ccode, I think you just said what I want to hear, I don't think I should have to have it shortened, from all that I've gathered so far.

You're welcome, All this info is still fresh in my mind, my swap was done less than 6 months ago and I'm helping a friend gather the parts for his, any questions, just yell and I'll try to answer.
