.092. .008bl

.087 .007bl

Some of these things fall together nice. Some can be a PITA. Looking at all those pictures, I think I would throw 083 or 084 in it, open the backlash to 10 or 11, maybe 12 if it likes it, and live with it.

If I get the coast center than the drive side is way off and if I get the drive center coast is way off.

I see that. That last set of pics looks like it's a little deep on the drive side and not too bad on the coast. That's why I was thinking - reduce the shim pack a few thou and put it together. I would still open the backlash some. Are these new? Street car? Are there numbers inked on them identifying them as a matched set? Did they come from a mail order or where?

It’s a used set that I ran in 04 that I changed out for 4.11. They are factory gears . I opened the BL to .010 and it didn’t make a diff. It’s going in a street cruiser no racing

Well, that matters. Used stuff is a pain. I was told long ago that when setting up a used set of gears, look at the coast side and ignore the drive side, since the drive side gets all of the wear. It is advice that has worked well for me. Based on that, the first set of photos with a .090 shim has the best coast pattern. Put that in with 8-10 BL and send it.

Ok thank you and thanks to all for
Input.
