so my rad is trash, cracked along the seam top and bottom... what is interchangable? i suspect 1967-1979 2x4'? see my sig for details about the truck.

 

The rads out of my 78 and 79 (400 and 351M) will fit my Son,s 69 SWB 360 flange is about 28 inches across. Good luck, George

 

I believe all 2x4 and 4x4 from 67-79 interchange except 6 banger which, atleast on my truck, had the hose connections in the wrong spots for a v-8

 

I agree about the 8s vs the 6s. I just swapped my 240 for a 360 on my 2x2 69 and had to do a new radiator since both upper and lower connections are reversed. Other than that I think that everything is interchangeable.

 

thanks guys, i kinda forgot about this post. good stuff.

 

28 x 19... is that correct?
