Questions on Install of Z1 Differential Bushing Kit

Flush to almost 1/16" deep in the front. You may have to install the diff to see if you can start the 2 front bolts to see if it's in the right spot. You want to snug up the rear nut and then try installing the front bolts. If you have trouble installing the front bolts. You may have to move the bushing in either direction. You always want that rear nut snug first. Because then the bushing is fitting into the taper of the stud.

Thanks Rusty! Any idea about the black metal washers that sit atop the stock front bushings? Should they be re-used or discarded? The instructions provided by Z1 make no mention of them.

I would need to see the set-up to tell you.

Okay, on closer inspection the washers are domed in the center in order to fit over the bulge in the upper portion of the stock front bushings. For that reason, I think they're specific to the stock bushings and I'm going to discard them.
As always, thanks for your help, Rusty. Much appreciated!

I did JL's poly bushings a few years back and couldn't remember how it was. Got a case of CRS. (Can't Remember Shyt)
