I can't find any where to decode the trans and rear. trans is a 3 speed on column and rear is supposed to be original. The trans numbers are as follows: 4 GM 691816 HR214789 H190 The rearend numbers are: HE1025 and 3657339 Thanks for your help! Last edited by chad's 5 window; 06/02/2010 2:26 AM.

Looks like rear end was built Oct 25th, which makes sense since trim plate shows truck built in Nov. Could that Muncie be original, with the August date? Also looks like it may of came from a 3600. Mine is a 3100.
