Hi, I just bought a Napa oil filter cartridge for my 58 Caddy Coupe deville. The Napa filter is a # 1100 and is about 3/8 inch larger in diameter that the old Texaco filter that was in there. Everything else look about right. Could the larger dia. be a problem? I plan to use 10-30 oil with it. Thanks, Larry PS: I need a decent rear right bumper end for the car, too.
