To get a good fit, the after market parts may have to be tweaked. I ordered a set from Moss and found the aluminum bracket to be thicker than stock. Still fit, just pointing that out. The rubber, which is identical to the rubber bumpers used for the hood, was not cut like the original.
An easy fix. If the ones you get do fit your car, cut wrong, not big enough, ect. Buy 4 rubber bumpers. Original rubber used a split rivet to hold it in place. This split rivet may or may not be reused. If not, simply use a rivet gun to attach a solid rivet.
1. Screw the aluminum brace in place. There should be two holes in the side of the chrome finishing surround.
2. Place the rubber on the flat part of the aluminum place and mark then cut to size.
3. Why buy four rubber bumpers? Measure twice and cut once, never works the first time on anything associated with a Healey. Need two rubber bumpers, buy four. Trust me.
