I feel like the metric ton nameplate was rare then as it is now. The metric ton was also denoted as the big ton with a sticker in the rear window. I believe those are reproduced at boxy jeep. I know someone on here was also 3D printing nameplates.

You’ll get good cooling out of 134a but nothing like modern cars that run it. The problem with 134 is it needs a big cooling surface to effectively work and cool properly. But at the back of the air box from the middle vent I’ll see temps in the 30’s. But once it comes out of the vent it’s probably closer to 40. Overall I’m happy with the performance as my MJ never had AC from the factory so anything is better than 110* out here. But it sounds like to me when it was converted, the proper o-rings weren’t used. Change all those out, probably the expansion valve too if that’s still rated for R12. Usually they are stamped with 134 on the block. And replace the schrader valves in the service ports while you’re at it so that way if you have a leak, it won’t be from degraded valves at the service port. I’ve gotten to the point now where I’m not afraid to service my own AC systems. Oh also in case you don’t know, 134a becomes acidic when in contact with moisture which will result in tt eating away at internal components. If you plan to do this all yourself make sure the dryer is replaced as well and that the humidity is low or very dry. Course don’t charge a system until you know it can hold good vacuum.

The 2.5L harness is pretty standalone. You will need only one wire and that’s the power wire to the fuel pump on the sending unit. And that wire needs to go from the fuel pump relay all the way to the back. I converted my 84 XJ to the Renix TBI and it’s pretty straight forward.

I may have a NOS reservoir looking for a new home if you can’t locate a reservoir or if you decide to go the 4.0L pump route.

Yes. Yes it does.

Headlight relays are an absolute must!

Im not proud of this fix but here’s the wire. I tested it and had to pull it back apart and taped the wire down to prevent it from moving out of the spot and jammed the terminal under the door cable. But it works and should for a while.

We have AC!!! I hate the rudimentary system AMC used. Especially the micro switch. Smart but dumb. Relay would’ve been better. But I jammed a piece of wire in between the brass that lost tension and the plastic and it operates like it should.

How did I miss this update? How interesting! Wonder if I made a similar mistake on my XJ and didn’t realize it. Could be why I smell and see excess gas down the TB. Huh. Now I’m gonna have to investigate it.

Oh hell in a hand basket. Ok I think this is manufacturer based. I once bought new ones for a member on here and one of the sides was orange. Like original orange. And the other was a brighter orange but not much brighter. As far as I recall, you can still get OEM but you might experience the same discrepancy. There’s probably some on eBay too. though you are on to something cause I’ve seen the HO years have a bit brighter yellow color for the markers but those new ones I mentioned were more orange. So it could be sun fading that we’ve seen. Part numbers are 56000110 and 111 if you want to look on eBay for orange ones.

No. But I got it!! when I was vacuuming down the system,‘I heard a thunk and then the gauge jumped and went back down. After trying to charge it. I did some thinking. I took the hose off on the suction side, vacuumed down the high side and heard suction. Ok expansion valve is good. Took off the valve from the compressor. Clogged. Ok. Took the adaptor off and found an o-ring had been sucked up. Wonder where that came from. Anyways I vacuumed down the system, made sure it held for a few minutes then charged it. And it did great. But now I gotta find where it’s not signaling the compressor to engage. I had to manually jump the compressor to get it to charge and man does it blow cold.

Well this blows. Or sucks depending on how you want to look at it haha HVAC jokes. But no looks like the expansion valve isn’t cooperating or there’s something that’s kind of stuck.

At least we aren’t treating the connector and control module like a NES cartridge haha.

Both I’m pretty sure. If I remember right those two numbers are halves and I clipped the two together and proceeded to modify it to the 2.5L.

Finally pulled the trigger on a HVAC vac pump. Vacuumed down the AC last night, held good vacuum and is still holding good vacuum. I should be set to charge it and have functioning AC.

That coolant bottle is probably the only thing crown makes that’s worth while. Ironically they don’t make the cap which I find incredibly odd but they’re a crappy company that doesn’t go the whole 9 yards for restoration parts. Like they have XJW headlamp bezels. That’s it. Nothing else XJW specific. But that bottle will last a long while. I had one. I think I sold it after I got a genuine NOS one

Oh yes I do know. I used that same set up. I had to modify it and that mostly involved cutting hoses to mirror the old set up. I doubt there was anything wrong with mine but it was brittle.

I think I had a servo fail me once. everything else was typically vacuum.

That one is still on eBay?! Hahahaha. We could probably make new ones for that cost.

I swear I saw somewhere that the GM ignition cylinders are not serviceable and a new one with keys was to be ordered. I could be wrong and they could flat out be serviceable and manufactures just used it as a way to move away from rebuilding lock cylinders.

Yeah it will be. All I know about the cruise system we have is that it was manufactured by Dana corporation. AMC got the special set up while everyone else got the Dana corp standard kit.

Oh ok cool. The whining could be from somewhere else but yeah it’s not a bad transmission. I haven’t had any issues with either of mine and think they’re pleasant to drive I think the only one I have issues with is my MJ and it’s 2nd gear. It doesn’t like to down shift at a certain MPH.

No it’s not that bad. It’s just a light duty transmission which kinda sucks. So when I destroyed my first AX5, the engine suffered no damage but sheared the input shaft right off the transmission. So if and when it goes, the engine will be fine. That being said, maybe it needs a fluid change and some royal purple. I have been running GL5 oils with no issue at all.

Score! I’ve always been curious about the aftermarket version of the tester. Yeah it’s the same but has more to it.

Looking good!!! Now we just need bumpers to be reproduced and we would absolutely be golden!
