Swap to t5

[62stepside longbox]

Hi everyone, a guy I know that works at a transmission shop has found a t5 for me to put in my 62. He is going to put on an s10 tail-housing so the shifter is in the correct location for a bench seat and a different input shaft so that it will work with the stock clutch. I will also have to put in a transmission mount. My question is what else will need to be done for the swap? I currently have a front motor mount with bell-housing mounts on my 261, will I need to switch to side mounts or could I just keep the front mount and bell-housing mounts? Will the torsion bar cross member make it difficult to install the transmission? Thanks
Nik

Oh forgot I also have to get a one piece driveshaft

You can upgrade clutch to 26 spline instead of swapping out the shaft. The bellhouse mounts work fine, I did add a crossmember on tailshaft but have a 406cui to work with. You can easily move transmission in and out. Driveshaft will bee 2" shorter, no need to replace whole thing. Sure there are helpful pictures on my build l8nks.

Thanks, sounds like it should work out pretty smooth. I thought I would need to swap to a one piece because I assumed that it would need to shorten it more than 2''. But that's one more thing to take off the list.

Will I need a different driveshaft yoke?

Just keep your original bellhousing and just bolt the T5 on the back just like the SM420 is. There is no rear trans mount needed. Yes you will need a slip yoke for the back of the trans.

Watch this thread and my website T5 page for an installation. I will be heading to VA next weekend to install a 1993 S10 WC T5 in a 1966 SBSS. I plan to document the installation. The T5 going in already has the Jeep shaft swap done. I was able to get my hands on a WC Jeep shaft so this thing is all WC.

Makes me think about doing the swap in my patina truck. Was going to go with a 700R4 but it might be ok with a T 5 in it. I didn't want to deal with a clutch in traffic all the time. Also, what years work? I don't know much about the t 5's.

Please see my signature for lots more T5 info.
In short,
Find an S10 T5 from 1993 or earlier. It must have a Muncie bolt pattern if you are using the old style cast iron bell. See my website for more details.

If you find a Camaro T5 with a Muncie pattern, they can be converted to have an S10 shifter. The S10 shifter position is required if you want to keep a bench seat.

Most old trucks have a fairly low rear diff. A 3.73 diff is common and the best T5 to use with the 3.73 is a T5 with a 0.73 or o.72 OD gear.

Lugnutz65: is there a way to figure out what my overdrive gear is? I thought it was a 0.76 or something like that but I don't remember.

If the T5 is out of the vehicle then use THIS method.
If it's got a metal tag then the BritishV8 website chart is fairly accurate but I have found it to be wrong many times.
Best way is to count shaft revolutions while it's out of the truck.
You can use an accurate tachometer too. Since 4th gear is 1:1 you can see how much the RPMs drop at say 65 MPH. If 65 MPH in 4th gear is say 2900 and then it drops to 2100 in 5th, then that would be a 27% drop which means a 0.73 OD gear.
