This post was approved by Jim Weise RnD Fabrication is proud to introduce our line of 1964-1977 A-Body Radiators, and our line of 1978-1988 G-Body Radiators! We make these here in the USA, using USA-sourced materials, and we are American owned and staffed! Each radiator is TIG welded by hand, and we never use any epoxy or plastic. They are constructed from aluminum, and we use dual 1" thick cores for a total core thickness of 2" (same thickness as a brass & copper 4-core) with an average of 16 fins per inch. These are a direct fit, bolt-in upgrade that uses your factory mounts (note that G-body applications must use a Cutlass style top plate for this configuration). We can build these for stock engines, as well as for LS & other engine conversions with ports in the correct locations for your engine, and we never charge extra for engine conversions. All units include a transmission cooler at no additional charge (specify when ordering). If you want one for an LS conversion, there is no additional charge, and simply specify if you want the steam port or not. Retail price is $450, and members of this forum get a discounted price of $425. 1964-1967 A-Body Radiators: http://www.rndfabrication.com/ABodyearly.html 1968-1977 A-Body Radiators: http://www.rndfabrication.com/ABody.html 1978-1988 G-Body Radiators: http://www.rndfabrication.com/Gbody.html Make sure to mention you are a member to get your discount!
