Ive been yo-yo'ing the same idea's. My LP30 is bent, the rd-30 arb locker has 3 of 6 bolts for the pneumatic cap sheared off, my axle eyes are stretching and all the mounts basically suck ***. I havent even wheeled it that hard. I've considered gettting a HP30, shaving off all the brackets and putting on a T&T truss with all the brackets and geting JJ's, chromo axles, etc... even with reusing my locker a HP30 well polished is still about 2200.00. After looking under my front end today for about 2 hrs trying to get those sheared bolts out and breaking off a screw extractor, I've decided to say F it. Im gonna source a 78 F250/F150 HP44 shave off the mounts, cut it down to 63" or so and weld on a truss, throw in a Detroit, chromo's and 4.88's, Chevy outters and run hi steer... Im tired of polishing.
If @ 1st you don't succeed, grind it, hammer it, weld it, drink a beer and try again.
