Fuel caps

'60-66 will fit the hole but the '60-2 clocking of the handle might be different. If you want the original type, you should be able to find them at Fall Fling. If Layson's is there, they've had them in the past. Steve's are a nice replacement cap that have the factory style look. There are usually a bunch of aftermarket ones on E-bay. Check your filler neck to make sure it hasn't been modified sometime in the past. I see more and more of those that have been ruined trying to install the later caps. Once you expand the hole bigger, the original one won't stay in anymore.
