No idea why it was moved to a TBI board...damn newbies.
Anyway, the only difference between 85-92 throttle bodies is (as far as I know) the linkage. GM changed the design of the tv cable, throttle cable, or something like that. I do know that later ones work on all motors...but earlier ones only work on earlier systems.
good luck,
