Re: Budget Build 1985 K20

So I ordered a champion 3 row aluminum radiator that was supposed to be a direct fit drop in. Well it doesn’t fit. Surprise surprise! The tank was too wide to accommodate the factory isolators and brackets. So I got some Prothane small block isolators and carved them out with a razor blade to fit the bottom mounts and that worked good. But the radiator is also about 3/4” shorter then the original. So I had some 3/8” thick aluminum flat stock laying around and I welded it to the top of the tanks to take up the gap so I could use the original rubber supports and brackets.

Don’t judge me on my aluminum welding. I don’t do it often and I really didn’t want to blow a hole in the tank!

Another task crossed off the list. I will be firing this thing up soon.
