Since my truck has some pretty stupid flex in the front now, as compared to it's previous setup, I was kind of worried about the driveshaft, but figured the shocks would limit the axle enough. I came across this looking for Brents old posts [ QUOTE ] Essentially all you need is an existing Spicer type 1310 CV to start with. You disassemble the CV completely. The Center section and ball pivot will be discarded. Purchase a 1330 center section and ball pivot, also purchase the Spicer conversion joints to go from 1310 to 1330 (standard 10 bolt rear to 12 bolt rear conversion joint). Reassemble with these parts. I haven't done this mod myself yet, Im still running the near stock Saginaw CV up front. [/ QUOTE ] Gwa? Has anyone else done this?
