TPI intake differences
Are there any differences on the intake bases throughout the years? I know fuel rails are different because of the cold start injector but what about intakes? The reason I ask is because I'm trying to sell the base and runners from the engine I pulled out of my '91 to a guy with an '87. Will it fit?

I think they changed the base plate in 1987. So anything from a 1987 car on up should work.
