S-10 manual box
I pulled mine from a junked 1990 S-10 (I-4 w/man trans). Any of the 1982-1994, first gen S10's should work. Check over on Maliburacing.com for the build questions (FAQ section) and it spells it out!

Was a very easy swap, just didn't like the feel of the manual box. But it make the 454 swap easy!
