I have two radiators I have picked up at swap meets. One needs a core and the other has the lower outlet moved to the drivers side to accommodate a different water pump. Both are 3443 969. My question is, could I salvage parts from a '70 or '69 etc to make these radiators something I would want to use? Would this even possible? Thanks

AFAIK that radiator is a 26 in. wide radiator with 3 rows of tubes for a 71 B body with a 318 or 340 motor. The inlet is on the top left and the outlet is on the bottom right.
So you should be able to use this radiator in a early 70's B or E body with a small block. Since it has 3 rows of tubes, it should cool pretty well.
As far as modifying this radiator is concerned: If you move the outlet to the opposite side (to use with a big block) be warned. You also need to fabricate a baffle in the top tank that redirects the coolant to the right hand side. if you don't, most of the coolant flows directly from the inlet straight to the outlet and bypasses a big portion of the core. Overheating guaranteed. Been there, done that.

It's a 71 318/340 B or E body radiator so used quite a bit. The bottom tank was probably changed to work with a BB.
