apdi 4387 was what i got, they now sell the apdi 4333 which is non ic, not sure if you can fit that in the ic core support, maybe someone has experience using the wider condenser, theres alot of manufacturers making universal parallel flow condensers by size that might allow for more size and im seeing oring fittings on most of those.

 

The 4333 looks to be a lot shorter but maybe same width as the 4387. The 4333 also works for the 1980 Mitsubishi 6 cylinder!
From what I have read, the intercooled condenser hasn't been available for years.
A universal condenser has threaded connections top and bottom. I'd have to figure out how to run the lines, hmmm.
Seems like someone in the business could put together a package to upgrade the AC system.
The condenser is 30" wide X 14" high.

 

I found one, a condenser. It's an OSC 4387. Looking at pictures of various manufacturers condensers, some of them do not look like they're parallel flow.
Ordered up an AC component kit. The only thing I didn't find was the AC lines so I will be taking the old ones to a local shop to get redone.
Rock Auto didn't show a condenser in stock but when I searched for "4387 condenser" I came up with the OSC 4387 at RA. I went back to the RA website and then found it but it wasn't listed in the vehicle search.
It has shipped so we'll see if it's right.
