FYI, I am going the other way. So if the petals from my 76 Vega will interchange with yours, we can just swap. Can anyone confirm this?

I like '76 pedals better because they do not have the small plastic wheel of the earlier models. I have a set to put in my previously automatic '77. When I converted the car I didn't have the '76 pedals, only had a set from a '75 with the wheel. So if the later car can use the earlier setup, the earlier cars can use the later setup. Just make sure you get a '76 cable because they are shorter than the earlier ones that use the plastic wheel.

The pedal suggestions are all good, but there are several issues you need to address about the S-10 transmission. If it's out of a 4-cyl or 2.8 V-6 truck the bellhousing won't fit(they use the FWD engine blocks). If it's out of a 4.3 V-6, the bellhousing would bolt to your block, but it's set up for a hydraulic clutch. So firstly you need an H-body cable clutch bellhousing, out of 2.5 4-cyl or V-8 Monza(no V-6 or 2.3 Vega; neither will fit your 2.5).
Also to be considered is the fact that the T-5 trans is a bunch longer than anything ever bolted into an H-body; this means having a driveshaft shortened. Other issues include the shifter location(too far forward to fit through thew hole in your floor), your crossmember will have to be moved or modified, lack of a place to mount the torque arm and I'm sure there's other stuff I've forgotten.
I hate to "rain on your parade"- I'm not saying it cant be done, just that it's a pile of work.

Note- the very act of listing all of these has made me realize I have some kind of problem.....

If the 5-speed is out of any early S10 I think they had separate bell housings as well as the old style Saginaw type transmission to bell housing mounting, could be wrong, I don't have the parts here. Can someone verify?

I was referring to the older ones with the separate bellhousing; I had forgotten about the later ones that are integral with the trans. The older style T-5 does have the "normal" Saginaw mounting ears on the front; that's not the problem, everything else is.

i used a t5 from an 88 camaro with the monza v8 bellhousing and the later pedal setup in my astre. the pedal bracket bolts up to the original holes in the firewall but on the early cars like mine i had to drill a hole up thru the cowl area to mount the other end of the bracket(simple mod) i used the later cable and wrapped it with a heat shield sleeve. as spence said you will have to make a new crossmember and shorten the driveshaft. in my early car i also had to make a little more room at the mouth of the trans tunnell around the top and gas pedal area with a bfh to clear the bell,the later cars have a bigger tunnell so this might not be a problem for you. get a good shifter like a hurst billit plus with positive shift stops as overshifting is one of the problems with the t5 and the stock shifter. with the camaro t5 the shifter will need the stock hole in the tunnell moved rearward about three inches but this will not interfere with the e brake handle.make an attachment point on your new crossmember for the torque arm and use a ford nine inch rear and buy a torque arm from justin at overkill race cars made custom length for your application. this will get you shifting gears! :th: here is a link to my journal where you can see picsof how the camaro t5 needs to mount to the crossmember and shifter position with a straight stick in relation with my knee as i sit in the car, viewtopic.php?f=20&t=26282
