I am trying to get A/C in my 1989 Ramcharger for the summer. I have a 93 5.9 Cummins with a Sanden compressor, but I am pulling my hair out with the core support. It has been changed.

From the looks of the paint staining it has a condenser shaped like this (Link)

I see that some parts places have two listings for a non-inter cooled condenser between 89 and 91. Some just show one. The bolt pattern is 39" across, 6 3/4" on the passenger side and 8 3/4" on the drivers side.

Anyone know how to tell the difference in the core supports or know if all of the condensers for 89-91 are the same?

Thanks.

 

im building a '74, and im going to use the '92 evap/h-core box, my plan I to go intercooled, and in front of that, a universal condenser, measuring as big as possible, and make adaptable hoses, for r134 bigger condenser is a must, check specialty ac places like atra

 

I take. From your comments that you did not do the conversion on your RC? You might still have a gasser rad support. Look on e-bay....there is a couple rad supports on there for non IC trucks. You can then compare to yours to verify things.

I can't recall right now, and I'm not at home to check my pics, but I think the AC lines between IC and non IC are not compatible. You might have to get custom lines made up?
