CAN'T FIND A HEATER CORE THAT FITS I have an A/C car with A/C deleted. I put a brand new core from O'Reilly's and the tubes were 4" on center. I "coaxed" it together and drove 2500 miles ok. Now in paint shop and bumped hoses replacing fender and leaked inside (doh!). Took it all apart again, and CAN'T FIND A CORE that fits correctly. O'Reilly's replaced under warranty, but I had them order two. The hose welds on one were poor, but both hose tubes were too close together. Ordered from Advance, same problem. Ames core also is 4" on center and they could not provide a solution. ANYBODY know where I can get a heater core with tubes 4 1/2 on center?
