Transfer Case Part Numbers

[HectorM52]

Okay, what are the differences in the transfer cases that have RPO Codes DZ, HP, & JK? There must be a difference because I think there are different part numbers for each RPO. Also, is there a difference between SyTy t-cases vs. Bravada or Astro t-cases? What are the differences there? I don't think or bolt pattern matters, but if the bolt patterns differed, I would love to find one that fits my tranny (T56). I have another thread about that adapter. Basically I want to research the t-case before I buy one! Thanks guys.

The difference are what year the T-case was install, 91 and earlier and 92 an up. Sy (91) & 89-91 Astro are both the same. Bravada and Ty the same also.

The don't make one to fit a t56 directly....

BTW I have a Syclone transfer case fs.
