My original 3 row core OE 65 dart SB rad sprung a leak & a tin of coarse ground pepper from the Quik Shop on the way home fixed it for a year! then it sprung another leak in another location so I bought an eBay Champion 2 row direct fit aluminum radiator & I had to redrill 1 mounting hole on one side & it cools good (nothing to brag about on a DD 318 though) & no leaks & was ~ $189 iirc including shipping. I'd by another Champion rad in a heartbeat
