I am rebuilding the Quadratrac transfer case
in my 79 CJ7, and can not find a source for the .070-.072 thick circlips that retain the output shaft bearings. The end play is much too loose with the standard .060-.063 circlips, and I would hate to put it together this way.
Can anybody help?  

I solved this problem by buying some standard 2.5 inch bearing retainer clips and ground them down to the needed thickness on a surface grinder.  The standard retainer is .078 inches thick so it can be reduced to the desired thickness needed to properly shim the thrust bearing.
