Not Ranked
David,
I had checked for some reason a while ago how much material was left in the rim at the bottom of the holes & it didn't seem like much was there. I phoned Bob & he confirmed that they cannot be deepened for fear of breaking through the front.
So mine at least are limited to a total length of approx .750".
Someone with a different backspacing may have deeper holes, but I believe Vintage only supplies 1 style of nut regardless. I am unaware if they have changed to a non-tapered ( flat bottom) style of nut.
Thanks Craig
