Friend of mine has a stock S10 with manual steering, looks to me like it gives him a pretty good workout....
What engine do you have, and will it equal more front end weight than the stock V6 in an S10? If so then I would suggest at least use the original large steering wheel and column (even if you have to find one), or go for the PS gear box.
As a benefit of having PS you can run a hydrobooster and have really good brakes too.
What engine do you have again?
