The 76 cj should have came factory with either the 258 6cyl or the 304 v8, t150 3spd trans, dana20 tcase, dana30 front axle and AMC 20 rear axle.. The AMC 20 has a bad rap because of the two piece axle shafts, (the axle flange is hold on by a big nut at the end of the axle) the nut loosens and strips. I have had many, many cj,s over the years and only one developed a problem. The 3spd should hold up to the 360 as it came stock behind the 304. the frame should be channeled and not boxed like later years which helps prevent rusting (76 was last year for channel frame on cj) but look for rust on the frame around the rear shackle mounts. Only real issue with the fiberglass tubs are GROUNDS, everything has to be grounded to the frame. Most body kits use a big grounding strap. I would shoot for around $5,000, if it were steel body it would be worth more. looks nice by the way
