Hi James - I did an article for the GMCMI newsletter #88 in July 2004.
Here is the article:
AIR CONDITIONING CONDENSER
It has been difficult for people to find a replacement condenser for our GMCs. The GM part number for the pre-May 1975 model motorhome is GM Part number. 3014916. That is still a good part number. This fits a 1968 to 1972 Olds Toronado and is an exact match. I found one on the Internet at www.acpartsnow.com, [NOTE: SITE NO LONGER WORKS] their part no. 104-25360 for $123.50. Some sites might have them for even less. Post May 1975 GMCs take GM Part No. 3034647. An extensive search indicates that this part has been discontinued and was apparently only for the GMC motorhome. I have found that you can use the 3014916 but the fitting on the tube that attaches to the short hose leading to the separator/drier is the wrong sex and the tube points toward the engine. I bent the tube forward and I took the short hose to a shop and had them replace the fitting on the hose with the correct one to match the tube on the condenser.
James - you will have to be careful bending the tube since it is aluminum. Do it slowly an don't try to make too sharp a bend. An alternate to bending the tube is just to have a longer rubber hose made up with the proper fittings so that the hose can be connected to the unbent tube which will be pointing back toward the engine. Other then the orientation of that tube the condensor is the same size and shape.
You might be able to find a condensor at the junkyard from an old Toronado. I believe this same condensor was used in some of the other large bodied cars such as Buick, Cadillac and others from that era.
Hard to find nowadays though.

It works if I give the r12 a boost from the little can, but I’ve found a leak (previous repair on aluminum tube from the condenser? before it connects with the hose that goes to the receiver/dryer). I’m just stubborn enough – cheap enough – to attempt repair. I’ve acquired an aluminum line splice from Amazon – by the way, best price – but now need a tube from a junker to fit with the line splice and thread into the hose mentioned above.

> As an example of my stubbornness, I’ve now acquired a Thermaflo pump to recover/recharge refrigerant along with a 30 lb recovery tank for my r12 to stay out of the way of the refrigerant police. Two more tanks came for r22 and 134 with the Thermaflo. I passed the open book exam and got my EPA certification for motor vehicle air conditioning so now I can stay within the law.
> Anyway, my main question is whether or not other GMC vehicles used a/c parts similar to what I have on my Kingsley.
