J20 build can i make it work?

[SirPaul64]

Slowly building my J20 and have a few questions. Im pretty sure this is not possible but id like to try. A guy in town is selling 4 interco TRXUS STS 38X15.50 R16LT less then 100 miles 500 bucks with rims. This is a steal id like to try and get them under my J20. I have a 4 inch lift thinking of throwing on a 2 inch body. Im pretty sure SOA would be the way to go but not gonna do that. I believe some have gotten 36s under a J truck with only 4 inchs of lift would the 2 inch body make it happen? No plans to wheel this one so only street use/hauling loads in the bed. Am i dreaming or can this be done? Im sure id have to regear as well. Anyone know what gears i have in a 74 J20?

Also im looking into new bucket seats anyone reccomend an aftermarket set that fits nice? If not ill just find something at the junkyard.

Thanks guys
