I havea 1996 blazer and was wondering what kind of manual transmissions fit on the 4.3 vortec and how difficult a swap is.Mine is an auto.

 

i plan on doing the same thing. i was told it is pretty standard . and to get a new column of a junker to get rid of the colmn shifter. also cut the drive shaft.

 

If I remember right, you need tranny(NV 3500), all your pumbing:master cylinder, slave cylinder, and lines, new computer and wiring harness.
