Hey guys looking for some advice here. The spider gears in my 88 Comanche rearend are chewed up and there's lots of metal in the housing. (Told to me by my mechanic). What are my options here? Rebuild it? Possible swap for another axel? Also what costs should I expect going each route. It's the Dana 35. 5 speed tranny. With 3.07 gears I believe. Thanks
