Bob,

U can drill the side bars on the radiator to fit the cooler but the screw came too close for comfort to the cooling fins. And then, the cooler lines on the AZ unit were at off angle from the ones in the engine bay.

The downsides I see to this are: a lot of extra hose to route, how that extra distance might effect pressure, managing heat from the hoses and cooler itself.

I am looking at the real estate in the wells under the headlights to mount two high efficiency coolers.. while I've got mine "apart", I'll see what I can come up with..

Rear is an option too!

Ok, resurrecting Dom's thread..

I've got mine pulled down. I have a stamped part number on the drivers side header flange.. 1909902BL.

Looking at both AZ and Ecklers, the condensers in the photos are a bit confusing. Both Ecklers and the AZ R-134 condenser appear to have similar inlet/outlet geometries. The AZ picture of a '90-93 condenser shows the inlet/outlet connections straight and near the center of the condenser. This would never work on my '91.

I believe Marc indicated that the R-12 condenser would work fine with an R-134 setup. If someone has the dimensions of the '94-95 condenser, that would help me decide how much Fab is needed.

I can make a set of 134 hoses if needed to mate to the 134 compressor. What I'm not sure of is, specifically how much wider is the unit. This would affect how it sits in the mounting well at the bottom of the front air intake.

Fyi, my radiator, while not leaking and no issues with cooling, appears to have been "cut" with a saw blade on the top! What the heck is this from, prior repair job?

Some photos attached.. condenser looks like a mess and likely has small leak in a tube as evidenced by the refrigerant oil covering about 1/4 of the surface area..[ATTACH][ATTACH][ATTACH][ATTACH]

One last note regarding AC Condenser replacement. I installed the Auto Zone condenser (Spectra 7-4306). I shortened the screws, placed the oil cooler and marked the holes to be drilled. Slipped on the screw clips and installed the oil cooler.

I test fit the unit to see how much I needed to tweak the hard line connections. Not too much and aluminum is easy to bend.

This is a parallel flow condenser with the same number of tubes as the OEM that I removed. The core appears slightly shorter, but the number of tubes is the same.[ATTACH][ATTACH][ATTACH]
