For you guys considering purchasing an "adaptor".....bolting the S10 T5 up to the 235 requires cutting the mainshaft about 3/8" AS WELL AS cutting the throw-out bearing retainer shaft (1-3/8") so it doesn't hit the pressure plate diaphragm fingers. The mainshaft cut is a breeze with an air cutoff tool (3" disc or in an angle grinder with a cut-off wheel) and the TO bearing retainer shaft can be unbolted, sawed with a hacksaw and the little internal seal can be replaced. Good insurance against an oil soaked clutch disc should the little seal go south. I don't see how an adaptor is going to correct both of these problems.
Secondly, finding T5's takes some "hands-on" action. Calling a salvage yards was a waste of time as their computers showed NONE and when I stood at the counter at one of the NONE yards, I could see 3 T5 gear shift levers sticking up on a rack. I bought both an S10 .72 box to back up the one in my 54 and a second Camaro box as a backup box for my hot rod....all for $300.00.
Also need to mention that it's really critical that you match up the T5 5th gear ratio with your ring and pinion ratio, tire height and the speed you select as "normal cruise." Be aware that there are 2 different common ratio S10 T5's...the .72 and .86 OD's. Failure to have these all matched up with the power curve on your 350 will negate having an overdrive transmission. Running a relatively stock 350 you'll want your normal cruise at about 1600-1700 rpms in 5th gear. I use this:
http://csgnetwork.com/multirpmcalc.htmlI've got some detail instructions on setting up a .72 T5 for a 235 in my Chevy albums and some info on mods to the Camaro T5 in my 40 Hot Rod album. You might want to check them out and avoid some expensive issues I had to deal with.
