Anyone know if a plenum from '88 will work with my '92 speed density setup?

I want to keep my stock plenum original and need to get another one to port and I found an '88 for sale.

Need to know so I can take it.

Searching the board brought up something about the '88 having a hole for the cold start injector and something different with the IAC. I know the cold start can be plugged up but have no clue about the IAC.

Thanks.

Yeah it'll work fine. You just have to add a vaccum fitting for the MAP sensor.
I put the ported plenum from an '87 on my '92, no problems.
