Single or double?

if you don't care about originality and aren't stickler for details, then 70+ is the way forward.

i have a 69 and to me the bubble top rad is what "makes" the look, so i'm stuck with the expensive stuff due to my own aesthetic choices. but i'm also operating from a position of already having a V8 radiator, shroud and clutch fan.

but, due to my hubris when i retro fit the AC out i'll be either buying an expensive bracket or fabbing one up. and the same if i change anything regarding my power steering or alternator.

if i was starting from zero, i'd certainly take a different approach and that would start with 70+ timing cover/water pump and the pass side lower radiator. depending on my state of cheapskateness, it would either be a mix-n-match of junkyard stuff from mid 70's to early 80's truck or i'd pull the trigger for a CVF kit and grind my teeth about getting it done while knowing that i could do it cheaper.
