90 throttle body on 88 car

Using a 90 throttle body on an 88 iroc.

I know the style changed from 88 to 89, what are the adjustments that need to be made?

It may not work...although I haven't actually tried it...due to the difference in IAC passages from TB to Plenum.

If you want to make a trade, I have a spare one from an '88 intake.
