The castings are identical across cars and trucks,
for the mechanical types (not 'vettes and later
drive by wire). The fittings differ, throttle cam
and PCV bung and the coolant nipples. I ported
a truck TB core and swapped my throttle shaft
and PCV bung onto it, for my SS.

I've got a TB off a 98Z for my 01 WS6 and the only thing differet is the throttle cam. Now neither one of these car have TCS so the are both 2 cable set up.

Get the one that matches your year's cables (cam
size on the throttle shaft). The casting, hence flow
characteristics, are no different (aside from how much
care you take with setting it up and any porting).
