Any body know if I can use any of the mechanicals from a 94s10 4x4 on a 95 or 96 Blazer 4x4. ie, trans, T-case, running gear, etc.

 

Most of these parts SHOULD BE interchangeable. If you need to know for sure, take (or call) both Vehicle Identification Numbers to any G.M. dealer and have them look the parts you intend to use up for both trucks. If they're exactly the same they will call for the same replacement part numbers. Sorry that's the best I can come up with for an answer.

 

What he said.
Although the intake wont swap from prior to '96 to '96 and after, unless you also swap the heads.
