Would anyone have any suggestions where the best place would be to purchase a NEW Radiator for my 1966 Dynamic 88, or what are your thoughts on an Aluminium replacement. Thanks is advance.

 

If you have the original and the tanks are good, can you get it recored by a radiator repair shop? Sorry I don't know enough to comment on the aluminum.

 

I use Spectra Premium CU302 in my 98. Alu with plastic tanks , have used this radiators in several
cars for many years without any issues.

 

US Radiator might be able to build an exact copy of your original. They did for mine, a '78 98. Granted I'm only just now getting it on the road but so far it's worked well. Not cheap but if you want it to be as good the original that might be your best bet. It's worth talking to them and providing info like what option codes and features it has.

 

I used a Cold Case Radiator in 75 Hurst Olds (W30 with 455). I could not be more happy. It was a drop in and dropped temps about 25 degrees. Order from Summitt and get free shipping.
