Simon, You can do this youself for the cost of a little fiberglass mat and the resin.

I think what you want to do is deepen the floors on the radiator exaust ports, to increase air flow thru the radiator. Correct?

OK lay the nostril cover assembly on its back nostrils up. Cut the bottom of the two nostrils sides with a hacksaw blade loose from the rest of the assemble leaving the base of the nostril opening attached to the body of the cover.The base being the end of the nostril at the top of each outlet when the assembly is right side up. Leave enough vertical wall on each side of the cut so that you can revit a thin piece of alum to it top and bottom. Also don't cut at the corner of the opening, save the corner so that you do not have to remake it. You now have the floors of both openings sort of flapping downwards when the nostril assembly is in its normal right side up posistion.

Pull down the floor to your desired new opening size and then revit a piece of thin alum to close the pie shaped gaps on both sides of the nostril openings. Drill several holes thru the alum pieces to alow the fiberglass resin to flow thru thus making the grafted on part stronger.

Cover the wound with fiberglass matting one side at at time so that the fiber glass resin does not run all over the place. About 4 thicknesses of mat will equal about a 1/8" thick when full of resin and hard. Mask off areas you don't want AFUed with dripping resin. Start out with small pieces and mix small amounts of resin at first if you havent done this kind of thing befor.

Make sure you clean and rough up all existing fiberglass areas that are going to be bonded to as in the comments above. Also sand the alum parts on both sides with 60 grit also.

When everthing is hard sand smooth and repaint.
Your end product will look as good as the orginal one and have bigger openings.
