Thanks. I figured the three would either be for Rockwell or Dana20. Makes sense they'd be Rockwell. The linkage/mounts on the most complete one is similar to what's on that complete unit in first picture.

I've never had (or recall seeing) a truck with that type shifter knob, with no pattern, on the NP205 shifter. Certainly the same as others at the bottom of shifter. Looks like it's from the era full-time was offered.

Does anyone recognize that first combination? Could it be '60s Chevy K/10? I don't know what transmission that is. I wonder if it's even GM, maybe Jeep or IH?

The codes on the two engines I have are WA (blue) and TJZ. TJZ is simple, only shows one possibility... '73 20-30 series 350 4bbl. Funny thing on that one is it has the early heads with no alt mount bosses. The WA could be '65 10-30 283 2bbl, '68 307 2bbl 10-20, or '69 350 4bbl 20-30. It has an early square bore intake, late heads with alt bosses, and valve covers for late crankcase venting. It's like someone swapped heads on these motors, but they came from parted trucks from different places. The WA still has flex-plate and torque convertor in place. I need to see if large or small bore. If it's a '69 350 it's a 4-bolt and so should be the TJZ.
