Cheapskate Cooling...

73 Duster with a 410 Stroker with as many mods as I can afford! LOL but with that said as much cooling power as I can get LOL
I like the reviews on this? I can make anything fit it's just an old slant 6 car that I can cut or do anything I want. Of course I don't want to do too much if I don't have to, and also I was considering cutting the opening in the core support a couple inches on either side?

That looks like a pretty good deal for a two row core with 1 inch tubes.
It doesn't look like they come with any mounting flanges though.
Also no trans cooler built in if that matters.

Whatever you get try to mount it with rubber grommets, because unless you have a core support of some sort these cars flex quite a bit and tend to break the metals at the corners around the core.
