I have a swap meet radiator that fits perfectly in my A-body and has plenty of core area/thickness. But the brackets locate it a little too close to the water pump for the fan I want to use, and big-block A-bodies are always tight.

After going to the one radiator shop in my town (any others will be 1-2 hours one way), I trial-fitted it today and I'm not sure he moved anything. In fact, I am suspicious that he just spray-painted it black!

So as usual, if I want something done right, I have to do it myself!

Are there any special tricks to relocating the brackets (obviously, keep the heat off the core or any other part I don't want melted)... Googling shows that most people are using 50/50 tin/lead solid wire solder and brush flux (basically, plumbing solder) and a small oxyacetylene torch tip. All of which I have.

Or is this one of those "leave it to the pros" jobs, and I should just find a competent shop that actually listens to what I want done. Thanks for any advice.
