318 Oil Filter ??

Part number for the shortie filter is:

NAPA Gold: 1068
WIX: 51068


I think this is probably the easiest option. I measured it and I get 19 1/2" from the edge of the mount to the back of the filter and 19" from the mount to the firewall.

If I do need to spin it..... does anyone have a part number for the gasket for the adapter?

I don't even use the 90 on my 67. Use the "straight out" filter mount (headers) and a 51068 Wix

I'll go this route if it's still too close. I think I can swap out the pieces with the truck engine if need be.
