Why buy used (problems?) when Summit has a set of 4.33's for $160 + $12 shipping or another set for $206 or a third for $266 - all Richmond's. No clue without spending more time with the specs what the differences are, but a used R&P plus the bearings and seals plus labor for something that might have been flogged - hard - just isn't worth the aggravation. I can understand trying to save a few bucks, but not in the engine/driveline where you need as much reliability as you can get. And 50-100 bucks - not worth the possible grief and pain to suffer someone elses problems.

OK - now I'll put my soapbox away and watch the NA$CAR Nationwide race

Thanx much prostreet. I will bid on the second set then. I also found a Timken rebuild kit on ebay for about $80. So those gears and that rebuild kit and I should be on my way (need axle bearings as well).

I really appreaciate all of your help on this (and every other question you have answered on here for me).

You may need to know which carrier bearing you have to get the correct kit.

I think it's pretty consistent though that the smaller bearing is used for the 28 spline and the larger bearing is used for the 31 spline. I will mic it before ordering. Thanks.

You also have to know the diameter of the bearing stub on your carrier. The old carriers were 1.6__" and the newer ones 1.78". The LM501349 bearing is for the small stub and the LM102949 is for the big stub.

Used gears=bad new us gear is available for around $112.00 off ebay good gears.With used if you don't get everything set exactly as it was ran you will have problems.It's like putting used lifters on a cam.The gears are already mated together and being off a little can cause issues.

Its actually pretty easy to set up a used gear set. and its not like using used lifters. I dont see and 430 ratio's for that price,but that would be a good deal if there was.

Look under imca in ebay they are common ratios available into the 7 range.When you set up used gears do you adjust the depth by matching the wear pattern?I've just never had any luck with used gears.

You still read the pattern the same,you just won't get that perfect swipe in the pattern. If the drive is high and the coast is low or visa versa,you would do a pinion depth change and adjust backlash as needed. Normally If you get the pattern centered on the coast and drive without running off the edges you will be fine.

I have a set of 4.11 gears that are hitting. And if you look in summit racing it does list 3 series carrier.

There is no carrier split on a 9". Your ring gear is probably hitting around the pilot Brg? You may have to do a little grinding to get clearance. Be cautious as you only want to take whats needed because that is a area that can break.

Some of the performance gear sets already have the inside edge of the ring gear ground so you don't have that problem.
