Thanks Dave, the rad was in the car(physically inside the seating area) when I got the car. I suspect something early 60's GM as it has the trans cooler bottom tank. I just made sure it fit and then had it re-cored. The top rad hose is from an 86 Caprice cut down some. I enjoy telling people the about all the different year/years of the engine componet and drivetrain area.............for instance........1968 Chevelle master cylinder.....1969 4 bolt main 327 block....1968 327 double bump heads......1970's edelbrock intake.......1967 Impala pulley's p.s pump bracket, 1966 Caprice power steering pump.......new old stock short neck water pump from 1963.... 1993 cs delco alternator, 60's Corvette valve covers, 1980 camaro HEI distributer, 1986 Caprice 700R4 trans, 1983 Cutlass drive shaft(shortened). Its just fun to let people know how it all goes together. Kinda like Frankenstein!! LOL!
