WANTED - A/C DISCHARGE LINE 90 DAYTONA

Compressor to condenser, with secondary line to receiver-drier. Also has the inline "muffler."

89 uses the same compressor and the same drier, however, the condensers are not the same, the condenser is 27 7/8" long while the 90 is only 24 3/8" long so the 89 hose assembly would be 3" longer, could it work???, and then the question is weather the mounting flange to the condenser is the same.

The 1989 condenser connection is the same center-stud setup as previous years and is sealed with an aluminum N-gasket. And yes, the hose assembly will be a bit long, but very manageable. Here's a pic of Four Seasons 55502 on my old K-car. It's also about 3" too long, but I zip-tied it to the suction hose to keep it from banging against the receiver-drier. Notice the Dayco hose on the Four Seasons part. It's actually a very nice piece.

Update on the A/C line...
Bought a UAC discharge line for an 89 Daytona from Rock Auto, 90 is nowhere to be found.
The differences...
1)Instead of the male/female mounting to the compressor using a crush gasket, the flange is flat with 2 green o'rings which looks like a newer R134A setup, however, this is totally stupid, the high side fitting they used is for R-12 so without buying another retrofit kit I will not be able to connect gauges to the high side.
2)The hose itself is longer from the compressor to the condenser, after fitting it in there the muffler sits right on the ignition coil, had to use a piece of rubber hose between the two so it does not rub/vibrate.
3)The hose from the condenser to the drier is shorter, so, the drier has to be relocated and it will no longer reach the fender to be bolted up, I will have to use spacers between the drier bracket and fender with longer screws to attach it, I also had to relocate the siren for my alarm which was located right next to the drier, it now is located on the other side of the car so the wires also need to be moved.
4)Because it is "stuffed in there" I had to place rubber hose around numerous parts of the lines to prevent rub through and vibration.

I rented the vacuum pump from AZ, however, my Son's R134A gauges are broken (we did not know, been ages since they were used) so now I have to hold onto the vacuum pump and rent R134A gauges, without the gauges I have no idea if the system is pulling 28" HG and holding before I shoot refrigerant in.

It is still a work in progress, hopefully this weekend... 🤞
First the radiator, now the A/C lines, modifications and "making things work" is a royal PITA.
