Newbie here! I have an 87 Raider 2dr that I won in an arm wrestling contest. Not really bragging, the guy was 72 and didn't want it anymore. The 2.6 runs about as much as a stock 2.6 can. I'm going to keep the motor, but will be doing some performance upgrades as time and money allow. I've searched, but can't find anything on wheels. I'm going to run 33x11.50x16 Gateway Buckshot Mudders. Lots of choices for 16", 6x5.5 wheels, but I don't know a thing about the back spacing. Can anybody tell me what I need to be looking for?

87 Raider, 2.6l, Weber carb, Gen II brakes and UCAs, KYBs, OME leafs, still adding stuff paycheck at a time!
