150 for an axle? Wow. No lockah, so we weld it but wait no shafts, so they go boom, what the hell would be the point over ifs? You can have flex with no traction and get no where or break on the way and that is no fun for a daily driver, but here are some additional costs for doing it on the cheap...
Oil pan, return, sump, dip stick and assoted goodies for engine...$100
shocks...$200
frame plating...$100
drive shafts... $100 (on the cheap)
rear springs and hangers for 63" chevys...$60
ubilt flip kit... $40
tires and wheels for new found glory...$500 if you find good used 35's.
Just a lil more money. He needs a lift, tcase skid, some 33's and a limited slip for the frontand keep his dd clean.
