26 inch ECP in a 68 Dart

I bought one of their 22 inch radiators. Nothing fit properly. So tall I can't use a lever cap. Had to grind out the mounting holes, and weld the other side of the holes/slots so a bolt and washer would fit. After all that, the stock shroud won't work due to the mounting rails on the radiator. Wouldn't cool at low speed. I had to hand build a shroud. Called them up,and got nothing. Run away. Far away. This is a 69 Dart Swinger 340.
Nice to know if they dont back it up. Did they claim you altered it?
