Hi, have a '72 s doing an engine and 4 core rad swap. I am looking for dimensions as to where to position the 4 core rad lower saddles in relation to the front and rear of the rad support where they get welded in .

 

Good question! I'm about to do the same with my 70 and would like to know as well. Anybody know??

 

They are spot welded in the same location. The tank position is the between 2,3 and 4 core radiations, the tank width is different

 

Now that I’m thinking about it, the 2 and 3 core tank width is the same, and so are the saddles. The 4 core tank is wider, which requires a wider saddle
