@Gordon Nichols posted:Alternatively, once I had opened up the hole to fit the VS grill, I fiberglassed in a length of 3/4" aluminum angle stock on each side. The grill was notched on both sides (left/right) to accept studs threaded into the angle stock to tighten everything down.
I just wasn't into gluing it down like Alan did (but that's a great way to do it, too).
This is exactly the way I did my CMC to VS grill change and it works great.
