The radiator I use will have to be bolted from the outside (front) of the core support, that was why I ask, and thanks dick, I would not have used his suggestion, I had a 67 2+2 w/302 all it did was overheat, till I put a Galaxy radiator in it... I too prefer cross flow radiator, I havn't got any decent recommendation s so I think I am just gonna order the 77 Maverick 3 core cross flow
