trying to fit my rear wings,from the front up to the highest point they fit snug against the body side,over the top and down to the back there is a gap about 8" long,one side is 1/2" the other is 3/4".
any ideas on how to cover said gaps?

Mine had gaps at the back till I tightened the bolts up to hold them on. I used some of the wide tadpole beading with slots cut for the bolts and it covered the gaps. Woolies sell it as hollow bead wing piping but the stuff I got at a show was wider than theirs.

Mine was the same , I built the edge up with layers of fiberglass mat and then filled the top surface .I also used some beading to fill the last bit of the gap.

this gap would make the grand canyon envious ,better get the cement mixer fired up
