I have a little conundrum. I am doing a whole driveline swap in a 96 Impala SS from stock to a 383, modified viper T56, and 4.10 gears. Its going to have to happen in stages unfortunately because my rear axle bearings decided to start growling at me. So the 4.10s are going in next week while its apart anyway, then the rest will happen later.

I want to do 1350 ujoints, so it makes sense to put the 1350 pinion yoke on while its apart, but then I'll have to temporarily use an adapter Ujoint until I put in a new fabricated driveshaft after the T56 goes in. So, I thought I'd wait on the 1350 pinion yoke until later, but after the crush sleeve is installed you can't do that right? Wont it change the pinion depth when I retorque the yoke?

What would you folks do?

rebuild it the way you want to now. then when you swap. just replace the crush sleeve and yoke. no big deal.

Its not a big deal and has been discussed here before if you want to search for the details on the procedure. I would rather get the 1350 yoke now and run the conversion joint. I think your rear joint is a Mech 3R which very similar to a 1350.

Oh.. OK. I assumed it was a 1310 stock but I guess I don't know why I thought that.

I'm just a fan of overkill. Its probably going to be somewhere around 400 hp at the flywheel so its not necessary, but it would be nice.
