The new one that is made to use r134a, NOT R12 like the original one is.

I have my original but will install a new aluminium replacement, but direct stock replacement, exactly same piece than original this is for 73/74 Charger https://www.ebay.com/itm/73-74-Dodge-Ply...aeVlC:rk:1:pf:0Aluminium disipates better the heat so should be better to get more cold into the cab, I guess. I hope my car will be working this year to check it.

I got an NOS unit for my car when I did it . . . . although the original in the car still looked good, I did not want to take a chance . . . pretty sure the OE and NOS unit were Aluminum . . . i was going to say the same thing. back in my junkyard ownership days, [1972-1984] we sold radiators [brass/copper] and condensers [aluminum] separately for scrap. i can't remember ever seeing a copper/brass condenser from any american manufacturer.

Good to know! I thought they were brass like the radiators are.

Now sure how a more efficient condenser would cool worse with R12 than R134.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

my original ( Charger 74 ) IS NOT aluminium... is iron I think that would be the compressor?

Is the same iron tube as far I could tell used on gas and tranny oil colling lines. But definitelly is not aluminium

The increased surface area accompanied with a stacked plate [modern] style condenser is a more efficient design than a tube and fun [old].
Unless OEM-like aesthetics take priority, I don't see why you would run a tube and fin. Aside from potentially being cheaper. there are two kinds of these... serpent tube which is the original kind and parallel tubes which has being told is more efficient ?. In my case I'm going original design but aluminium just right to keep same original look.

Is the same iron tube as far I could tell used on gas and tranny oil colling lines. But definitelly is not aluminium i have seen fittings of a type of steel silver soldered, or brazed, onto an aluminum condenser tube. the reason being, that steel and aluminum will corrode together, making removal of the threaded fitting impossible without destroying one, or both threaded fittings. we always chopped those off with bolt cutters before tossing them in the scrap pile. maybe your condenser was like that ? an iron condenser would weigh a ton [figuratively speaking], and i would think as thin as the tube mass is, would have cracking issues from vibrations that are always present. maybe export stuff was/is different than anything i have experience with ? or possibly, your condenser was a light weight steel tube design ? occasionally, we would run across one of those, but could immediately identify it based on just how heavy it "felt", as opposed to the "normal" aluminum condensers.

The fix/weld was made in fact with acetylene gas and copper wire! ( dunno how you call that kind of welding job ). That is not posible with aluminium.

( my car is 1k miles from home ) not doubting you at all nacho. just stating my personal experience. today, there are so many methods of joining, or repairing, unlike materials, [with, or without heat] and since i wasn't there at the time, i can only guess. my only question is whether your original was "iron". i'll bet our individual interpretation of material is what is causing the confusion. "iron" to me is usually a part made of the same [type] of material an intake or exhaust manifold is made out of, or brake master cylinder, of which parts are cast. to cast, or form, an "iron" condenser would be quite the task, plus be brittle in use as i have previously stated. steel, on the other hand, would be easy to fab into a condenser, and be very rugged in use. i'll bet that is what you have, and i have lost that fact in translation. sorry if i have unnecessarily ruffled your feathers ! that was not my attempt. please forgive.
