i agree with jerry . 9i have a aftermarket alluminum rad in the 92 callaway car and it doesnt seem to help the cooling over my 90 with a stk rad. the alluminum rad is much thicker which can make it alot harder to get airflow through it at low speed . if it were me id buy the stk rad and maybe a new water pump just to make sure everything is up to snuff . jerry gaskets has the water pumps for sale at a decent price
