The you-pick nearest to me I noticed has a 1989 S10 with a four and a manual trans, I didn't check to see if it's a T5 or not. Well, I kind of did, knob was missing. If it's worth pulling to sell I'd certainly go get it, I had one before with the oddball T4 - it even had the bulge for the OD gear but no OD - and I did pull and later sell that trans for way more than I expected to get for it.
