Quarter panel to wheel house-sealant?
 

I just put new quarters and outer wheel houses on the 66. The ones I replaced were so bad I could not tell if the joint where the lip of the wheel house and the lip of the quarter meet were sealed. Are they just spot welded together and left alone?

Thanks, Jeff

Put some 3m Seam Sealer between them to stop water from trapping it's self between the two pieces of metal.
