with the texas summer just around the corner, i'd sort of like to get my k5's a/c working. it looks like the po jabbed a screwdriver into one of the 180 degree bends at the end of the condenser coil. needless to say, this makes it a little tough to keep freon in. a new coil costs way more than i want to spend, and most junkyard coils i've seen are pretty trashed. anyone soft soldered new pipe onto one of these coils and had it hold pressure? i worked commercial building a/c, years ago, but handled the electronic/electrical side more than the plumbing. plus, automotive a/c is a little different. can't hurt to ask. also, i have a sticker on mine that says it's compible with both r12 and r134a. that's sems a bit unusual.
