The steering column wasn't that bad but did require mounting it a bit higher than normal so the brake pedal would clear some of the switches. The S10 brake booster is a dual diaphragm design that works better than the stock power brake unit. It does require making a fairly simple custom mounting bracket. The GM blower upgrade makes the heater work much better than the stock motor and is fairly easy to do.
All have to watch out for those items and see if i cant do the same thing.
