My car has 3.25 rear gears which mean it needs some help in the performance department. My 3.70 spare 9" needs a short 1310 yoke and of course, set up (there is no spacer, crush or solid). The 3.25 has a solid spacer and shims but my question is, which is better/easier to use? I don't race nor do I need to disassemble this rear end. I do have a spare crush spacer that can be used (assuming I can find it)

Anyone have a spare 1310 short yoke they would like to part ways with? Or do I just do the Currie thing?
