OK, what in the world have I done wrong?!? The sheet is "the right size" but the carcass does have a bit of flex in it (seems a few mm wider at the front than the back, although lockdown bar fits just fine).
I've got the side receiving channels and it BARELY hold the back. Interesting side note I noticed the rear receiving channel is only 58cm wide.
Guess I'll just need to get another one cut at 614mm.
Anybody in Melbourne want a sheet of toughened WideBody glass for $50?
might be interested but its required for an older SS embryon so id need to measure to see if it would fit. Will pm you asap on yes or no if that's ok.
