I made a smaller hole and made a stainless plate to go over the hole ..bit of a hack job but plenty of room to do stuff,need to deburr the edges as they are a little sharp.
Personally I thing small is better.
My big hole the fastening plate I welded in is 16 gauge (that's .060, the stock metal is 20ga or .036) and the edges are all 1/2" rounded over so there's no sharp edges.
The rounding over also allowed me to tuck the cut to fit sound pad into it.
I used 15 1/4" rivnuts to fasten the cover.
I had a smaller hump cut out from a donor, as I was going to do the small hole, so I welded it to the hatch cover and my hump area is now double thick.
It may be overkill, but it's plenty strong, I'd say stronger than the original.
I wanted to be able to remove the front engine surround, service the carrera adjusters, time/service my dizzy, belt and replace my alt without removing the engine. I know can R&R the front engine surround tin in car, as I've already done it.
I also dropped a socket into the hell hole, I just reached in and grabbed it with ease.
For me bigger is better
