Terry,
The bushings that come with the kits are perfect for what you are talking about.
Dave the ONLY cut out markings you can trust are for the, VENTS, headlights, doors, nose and lower nose vent BUT
always leave yourself about a 1/4" or a little less.
DO NOT TRUST THE CUT OUT FOR THE WINDOW FRAMES! cut these out totally - well inside the lines then match up the window posts, one at a time, to fit to the frame. Remember the windshield frames
DO NOT TOUCH THE BOTTOM OF THE COWL BAR BRACE. They will/should come within 3/32's though, but not touching. They SHOULD fit tight against the angeled 1/4x1/4 steel welded at an angle on the cowl bar though.
As far as the cut outs are concerned for the side pipes, I put the body on as far as I can get it withou stressing it, then cut out for the pipes leaving roughly a full 1/4" all the way around.
<More a little later. I've got to contact my litle birdie!
