EZ, I put a tube grill on my '90 a few year ago. Last year I mounted a IC off a '99 PS out front of rad & AC. I rebuilt some brackets & spaced the tube grill out 1"-1 1/2" IIRC. Then I spaced the thingie....whatever it's called....the tin work piece across front down under grill & under headlites & wraps round to & screws/bolts to fenders. I spaced this piece out 1". I used some black hard plastic polyurothane stuff I found & wittled, filed, sawed, sanded, etc till I had it shape fit to go between the fender & the tin "thingie"....turned out looking pretty good. if I say so myself
I didn't have to drop or space the sway/torsion rods any. & I didn't have to remodify the hood latch either.
I built some mounts for the IC & cut holes down, on each side of the radiator, sorta like in the link "Let's Talk IC"
The IC sits about nearly 2" out in front of AC, behind tube grill.
I have my IC inlet & outlet plugged because I still haven't run IC tubings & got them hooked up yet....mostly waiting till I can fab hook-up to "soupbowl" inlet.
Lord help the folks here in Central Oregon when I get it done....they already think I'm nuts now!!!
