2-bolt main cap options

Pro-Gram use to make them, but no longer have them on their website. I have been unable to find anyone else who offers them. I am also looking.

been having problems trying to find 2-bolt. don't want to go the 4-bolt way. and not that keen on a girdle.
motor has already made 640 rwhp. s475 turbo. ate a piston on the dyno when water/meth failed.
what about using 4-bolt, but using only 2 bolts.
