Kent Moore Type "O" Differential Rebuilding Tools

Not sure if this is the correct place for this post since technically it's for tools, and not parts...However, I'm interested if anyone has complete Kent Moore tool kits to rebuild Type O differentials and is willing to sell the kit. Per the 1969 Service Manual, I'm looking for the following items:

J-22388 Pinion Seal Installer
J-8614-1 Holder
J-8001 Dial Indicator
J-21777-21, J-8619-12, J-8619-13 Pinion Depth Gauge Plate Kit
J-2235-1, J-2235-2, J22535-1 Pinion Holding Tool Components
J-21777-6 Dial Indicator Pin
J-21777-1 Gauge Shaft
J-8619-10 Gauge Disks
J-6133-A Pinion Bearing Installer
(Note: I already have the axle seal installer, which is why it's not listed)

I'm also looking for the differential housing bushing removal kit:
J-21474-3, J-21474-8, J-21474-16, J-21474-4, J-22545, J-21474-12, J-21474-8, J-21474-4

Lastly, Looking for the J-5395-01 rear seal (tail shaft) installer for M20/M21.

Thank you for any assistance you can provide - Rob

I would have to double-check part numbers, but I'm sure I have nearly all that you need. I changed out my Diff a few years ago and used all the OEM Kent Moore tools I could find. Following the procedure in the manual, and using the correct tools Worked like a Champ. Had the clearances and backlash nailed down on the first try! If you still need anything reach out via PM.

Hi Rich - I would be interested if you have the tools in my original listing. I'd like to do the same as you when I rebuild the rear end in my 69 W-30...use the exact same tools and following the service manual procedure. Please let me know what you have and are willing to sell.

Rob, I'll check the list today and let you know. Once I rebuilt the rear end, I no longer need them.
