Thank you both for the help. I will get my ducks in a row before I spend more money on parts. The S10 is a 2000 ZR2 4x4 extended cab. The only good thing I see so far is if I use a 3/4 ton box the wheelbase will be perfect without cutting the frame. The tires are brand new 31 x 10.50 15s. Maybe that will help fill up firetruck fenders.
