Before & After - My 1993 K1500

The VSS that is on the tail of the t-case won't work on this setup. I had to drill and tap the t-case adapter for a VSS. This will keep the correct speed even in low gear so I don't have messed up shift points. The t-case has a switch that sends a signal to the PCM so it knows it's in low gear, but the new pcm doesn't have this signal so I can't use it.

My tie rod and steering ram was behind the axle, and I had minimal clearance between the ram and oil pan on the old engine. The 5.3 will be moved forward 1" because of the new t-case adapter is 1" thicker. So the tie rod and ram had to be moved up front for oil pan clearance. Mark, aka Waffle, moved it up front for me. Now I have to watch out for rocks hitting the tie rod. The plus side is I can lower my bump stops some since I don't have to worry about my oil pan smashing my ram anymore.
