Looking to restore factory a/c on my 1986 supercab with 2.9l. Can't find any reference material i.e. pictures to figure out what brackets maybe missing. All I have is the front cast aluminum. Any help is appreciated. Thx, RFD2

Keep your mind like an umbrella, it only works if its open... Continually learning.
Have you checked the local junkyards for old RBVs with AC?

Pertinent info from the parts book:

Yes and to no avail so far. Thx for reference material. The pics and parts illustrations are very helpful. Now I know that attempting to fabricate something is not practical.

Toonces drives a Ranger . . . . just not very well.
"If it were me".

First, get an accurate assessment of what is missing.
Two major points to keep in mind- the original system was R12, and you'll need to upgrade to a newer refrigerant; AND, most of the original components would need to be replaced anyway with new parts, due to wear and/or incompatibility with the new refrigerant.

The info that @85_Ranger4x4 posted will help get you to that point. Also be aware that there was factory-installed AC, and dealer-installed AC which had differences between them.

If the truck has missing or destroyed AC parts, going back stock will likely mean tracking down some of the bits and pieces, and then having to buy more parts as new for the reasons above (compressor, hoses, drier, orifice valve and condenser at minimum, and likely the evaporator too).

At this point, again "if it were me", I'd look to see if any of the aftermarket companies offer a "complete kit" package for a first-gen Ranger. Just google "aftermarket automotive air conditioning" and there will be several companies you can check with. If your truck had factory-installed AC, look for a kit that includes a new original-style evaporator to fit in the original location, and you'll need to determine if you'll need the "mount and drive" components for the compressor. What you won't need, probably, is the AC/heater control head and ducting that's inside the cab.

Hope that this helps, and gives you an idea of other possible options. If you'd like, post some pics of you have, especially the evaporator case on the passenger firewall and the engine compressor mount, and we might can pin down more specifics for you.

Good luck!

Once you get past the bracketry and evap housing pretty much the entire factory system is very available new aftermarket. Compressor, hoses, condenser, evaporator etc.

FWIW I am converting my truck to A/C and I am sticking to the factory system the best I can (with the exception I have a non factory powerplant)

Actually, you've built a Ranger like the factory SHOULD HAVE. I really like how well you've done that truck.

Thx for your advice. The "if it were me" is exactly how I'm going to tackle this. I'll post pics asap. I'm reasonably confident it's factory a/c, but you can be the judge.

Aftermarket sources being LMC and rock auto? I'm assuming. Any others you recommend? Also, did you swap in a small block in yours? I'm thinking about the same in mine eventually. Thing is, I'm in Phx, Az, without a/c it's seasonal driving for sure.

"aftermarket" being dealer added or one of the kits aimed at hot rodders.

I don't really even know why the dealer setup existed. It literally does the same thing as the factory stuff but everything but the evaporator housing is different.

Yeah, mine has a 302. 96-01 Explorer belt drive. Currently need to reroute my oil filter relocation hoses (hoping to just go to an Explorer oil filter adapter) so I have room for the compressor.

Mainly, for PROFIT!

In the mid '70s through the early '90s, when I was doing automotive aftermarket, car dealers would order a lot of stripped units, then have companies like I worked for "preload" the strippers with stereos, pin stripes, paint and fabric protection, and they would make a LOT more markup on the add-ons versus the profit they'd see from the same factory accessories.

Then there would be further "upsale" opportunities when the vehicle sold. Tape units or upgraded sound systems, CB radios, power antennas, cruise control, fog lights, sunroofs, air conditioning, and later cell phones.

It was kind of a racket. Buyers pretty much had to take the preloads, and low quality goods and half-ass installation caused complaints. The car manufacturers started cracking down on the practice, and the technology changed anyway so that the practice went away. I guess that I was in it in its true "glory days", and it was a fun way to make a living.

The dealership parts counter also sold accessories (as in the dealer installed AC), as the Parts Dept. was also a profit generator. But the aftermarket was cheaper, in the parts and especially in the non-dealership labor cost.

As Paul Harvey used to say, "Now you know the rest of the story".

Thanks for the pics.

Your truck had factory-installed AC, not dealer-installed.

Looks like the mount and drive may all be there, except for rear brace (19D943 or 2889 in the drawings above).

Firewall pic, the accumulator/drier is missing, and the evaporator core has been open to the elements, so it's better to be replaced, too.

Thx again for the info, at least it seems like I have more than I thought for brackets. Everything else I was planning on replacing.
