Radiator Support
 

Can somebody please post a picture of what support is needed for a 3 core radiator in my 88 IROC Z. I've tried finding it online but I keep getting 2 different pictures.

There was only one radiator cover that come with these cars, its the same one on the 4 cylinder car as the highest performance 1LE 350 cars. When members go with thicker radiators we usually end up making one from metal. Mine is/was an Aluminum channel that I cut the back off and tig welded it at the correct angle, guys like Twin_Turbo have some type of steel bent in a metal brake. Another member on here simply made an extension piece that was an inch long that screwed to the four front bolts on the core support that allowed the cover to sit back a little more.

You can also trim the rubber isolators (4) to about 1/8 thick.If you have AC there is another rubber piece between the rad/cond, those (2) can also be trimmed down.This alone was enough for my 3 core to fit.
