Hi George,
I used the driveshaft out of an 85 S10 shortbed pickup. Had to cut it down 1-1/4". Later on decided to re-center my 54 AD rear end in the wheel well.....needed 1-1/4"!!!!!
I am running a 235, correctly mounted, an 85 T5 and a Camaro diff and would suggest that you try the S10 one piece short bed drive shaft. Didn't have to change the rear universal.....bolted right up. Not positive, but I think any of the short bed S10's up to 89 (all mechanical speedo's) would be the same. Hope this helps.
Dave
