Radiator and A.C. Condenser replacement

My OEM radiator has a small leak in it somewhere; I have not had the time to change it out. Before I do I want to change the A/C Condenser at the same time; after getting the R-12 purged from the system so I can get a new condnser installed. The original owner did not take their time in changing out the original 1984 350 from my 1984 K20 Chevy Suburban 3/4 ton. The A/C/ line to the condenser is "crimped" for lack of a better term) at the top. I have been looking online for a new one. Any suggestions? I also have to change the tranny cooler as well as it has a small leak that I observed after I pulled the original grille out which was busted up pretty bad.

Make sure you completely flush the AC system out with a cleaning solvent also. R-12 takes a different oil in the system

I don't have the equipment; (or space) to flush the A/C system out; I will be bringing it to a shop for a full removal so I can change the condenser and when I do get the condenser in I will have the system changed to 134A

I just changed the radiator today and the transmission cooler. The A/C condenser has a ton of "mummified oil" all over the front of it that also went through the transmission cooler that I changed out; it was looking bad. I will be working on the condenser next spring.

I also got the headlight pigtails replaced as the original ones were falling apart. I don't have headlights; I have tail lights, markers, turn signals. Where do I look for the headlight ground; is it inside the truck under the dash somewhere or is it under the hood??? I also put on 4 new headlights as well.....

What do I use for a cleaner to flush the condenser? I also lack the proper tools to do the job....
