FortyNine,
I went to a couple of pick a part type yards last week in the LA area, (Sun Valley). Every one of the s10's had already had the engine & manny tranny's pulled- I mean these guys must be circling like vultures because the date of delivery on most of these trucks was the first week of March. I did see a couple of automatics still sitting in trucks and blazers, but no T5's.

I hope you have better luck.
