Recently my compressor grenaded in the Burb, so I ordered all new parts to go back in. I ordered an APDI/PRO 7014544 condenser because I have one in my Tahoe and it's the largest drop in parallel flow condenser available for these trucks, when I opened the box, a Spectra 7-4721 was inside the box(I have another thread on this matter), the 7014544 is a 1" thick core, the 7-4721 was under 7/8" so I sent that condenser back, and ordered a UAC CN1635PFC. It's a thinner core(roughly 3/4"), but is 5" wider, and only about a 1/4" shorter.

I looked at Leroy's thread( https://www.thetruckstop.us/forum/threads/slight-redesign-of-a-c-system.43197/ ) and he used a 00-13 dual ac GM condenser. I considered it, but if you look at the fittings on it, I would have to have them cut off, and fittings welded on right at the core to have any hope of fitting it in with all the stuff I've already done to fit the intercooler in. And I would only gain an inch of height which may cause it to interfere with the supports I welded in.

I have 2 ideas in mind for how to connect the UAC to my stock lines. Either use the metal lines off my old condenser and have adapter fittings welded on, ir coldhose shows metric fittings to connect to my old lines and then I can use a #8 & #6 fittings to connect to the UAC. I will figure that out next week hopefully.

The UAC CN1635PFC

A stock 94-02 single air parallel flow condenser(I don't have a dual air serpentine left around) for comparison.

Thickness difference.

Modern parallel flow design with 8mm tube spacing. You can see how many more cross tubes there are in the modern cooler. And the UAC has universal mounting rails on all 4 sides.
