An original-style radiator Radiator will more than suffice.
Dave in MN. Minor point of correction. There are two Ken's in Texas. Ken Davis is the one on Ft Worth that builds A/C units ans shock kits. The Ken refered to in your post above is Ken Parker of Van, Texas. I used to build the F150 OD kits and post regularly here on FB. Maybe i need to start signing my post KenP isntead of just ken.
