chevy crew cab monster truck rockwells

selling my 79 crew cab. its got a 99 fuel injected 7.4motor that runs on gas and propane with a th400 trans. four linked on air bags. has already rear disc brakes. still has the front drums. have new seals and boots for the front axle. have not installed them. i think the rear axle bearings need to be changed. makes noise once i hit 35mph. not sure where its coming from. was going to get another rockwell and switch out the gears (3RD Member)but never got around to doing it. new rear drive shaft. still needs the front drive shaft. I have more pictures on my ig before and after the rockwells@79bigblue
