I bought a 12 bolt rearend for my 69 Z and someone has welded the spring perches in the wrong place. I am going to get a new set and weld them in but my question is, will the driveshaft that worked for the 8.2 10 bolt work? It bolts up but with the pinion angle so far off, I'm not sure if it is the right one. I'd like to have all the right parts before I take it all back apart. Thanks, Greg
