Core support ?

[RangerXP700]

I have a 1992 w250 and I need to swap the cabs out now because of a tree versus truck incident, and i have a 90 150 cab.. its from oklahoma,solid but has the dreaded rust on the roof. Anywho, just wondering if im going to have to get a core support specifically for a diesel or can i use the one from the 150. Any help is appreciated. Thanks

You need the one from a diesel, after '91.5 for the I/C.

So if one has a non IC truck,I'd be able to use a core support out of a '87? I really prefer the grille on the '87 over the '91-93.

i think the radiator mounts different. with that said, my 83 crew had a gasser core support that was hacked to get the big ic'ed radiator in. it was jank, but it work.
