Radiator that fits without breaking the bank ???

[Green Machine]

Need a 4 core radiator to fit a 1971 C20 to repalce the factory 4 core. Needs tranny cooler lines 12 inches apart and a 3/4 in. heater return fitting.

Past experience - ordered a 3 core 2 years ago for the 1970 from radiators.com or their cousin. Fits OK except the top metal bar is inverted and holds the fan shroud about 1/4 inch from from the brackets, fixed by using 1/4 nut as a spacer on the top screws, not the best looking fix but it works.

Present experience - ordered a 4 row from Rock Auto - CU369 was the number I think. All was good, tranny cooler lines 12 inches apart, fit the pads ok, lower oulet was curved, but had the same inverted metal piece at the top that pushes the shroud back, just like the one for the 70 and had no heater return line. The killer was it was damaged in shipping so I sent it back.

They sent out a nice looking aluminum piece with plastic tanks, but it would not fit the mounts, the crimp to the tanks make it too tall and wide to fit the brackets.

So here we sit with a leaky radiator thats not worth fixing and don't know what or where to get a good one that actually fits without costing 3-4 hundred bucks.

Any suggestions ? I also want to get a new 3 core for our 68, but not if it fits like the one we got for the 70, so I really need 2 that fit, a 3 and a 4 core.
