Ok, the condenser is 30" wide by 18" high. I have no idea about orifice vs expansion....I'm A/C stupid, when it comes to terminology, but I took pics. You can see that the condenser attaches to has attached tabs that attach to the core support.

By the way, the B-150, from which I pulled this stuff, was double-row pulley.

The biggest problem I have found with the JY hunts is the use of a different compressor with the 2-row pulley. That is because those units have smog pumps, and mine does not. The smog pump models place the compressor just right of center, while mine would be just left of center.

I hear there is a JY across town with a lot of old MOPAR in it, so I'm going to check that one out soon. It would have been tomorrow, but there was recently a death in the family, so I am now planning a road trip in my GF's car. Interestingly enough, this entails fixing a couple things on my old Chevy truck because, while I could live with the annoyances, I won't leave her here to drive our infant around in it for a week unless its 100% right for her... plus hers needs an oil change before I head out.

Yeah, this B150 did have a smog pump. I took all the pulleys, as well as the A/C compressor the alternator and the 4BBL air cleaner assembly, but I left the smog pump for obvious reasons.

I like the idea of having two sets of belts for this beast.

Tomorrow the Mrs. and I are pulling the Monaco on the driveway pad and positioning it in front of my garage. I might even go get the engine tomorrow, if we get everything done in time.

The one thing I'm dreading is re-installation of the black tank. Inca Plastics still had the original mold, so I know it'll fit, but I've never had to plumb one before. What's really stupid is that the gray tank is forward of the road-side dually wheels, and the only thing that's plumbed to it is the kitchen sink; the bathroom sink is plumbed into the black tank, and the shower was plumbed so that it exited right in front of the black tank drain, which required use of a "blue boy".

Since the original black tank had extra unused fittings, which would have allowed the shower to be plumbed into it, and because the bathroom was already plumbed into it, my plan is to plumb the shower into the black tank, which also has these same extra fittings, because I really don't feel like toting around a "blue boy".

It sounds like your gray and black water system was modified by a previous owner. I like separate gray water tank(s) for sinks and shower, with a diverter valve so they can be dumped separately from the black water tank. (Most government regulations allow more options for dumping gray water, in addition to using a dump station.)

I'd start by determining what would be best for you, especially in terms of dumping the tanks. (i.e., dumping the gray water tanks separately and/or being able to dump them into the black water tank.)

You'll probably find you need to dump gray water more often than black water.

I'd also catalog your drains (including toilet) and fittings on your tank.

It's possible to add fittings to plastic tanks. If you find you need to do this, I have additional information available.

Oh, how I love how older motorhomes were designed and built ... about as much as having another vasectomy in one of the world's worse earthquake zones.

I figured that was the gray water drain ... the off-white garden hose connection gives it away.

Down vent on the black water tank isn't good ... vertical vent, through the roof, is better.

Shower and bathroom drains aren't bad but I'd prefer to be able to hook up a hose (maybe a garden hose) to divert the gray water away from the motorhome. (Especially if I'm in an improved campsite.)

I assume the black water vent exits the top of the tank and does a U-turn downward? If so, and it's exposed to subfreezing air, frost could build up in the vent tube. Enough build-up could block the vent, forcing sewer fumes back into the motorhome interior.

A vertical vent is mostly inside the motorhome, effectively preventing frost build-up.
