4 bolt mains
I remember seeing an add on eBay a while ago - maybe more than a year ago- from a guy in Oregon that would ship back and forth and do the deal for around 1300 bucks.
I have a dove block and believe it has webs big enough to allow the extra bolts.
Thanks!

Looks like $500+ with machine work. Your building something that needs 'em?
ON EDIT: Sorry, I see you are looking for a machine shop to do this, didn't find anything but maybe through one of those links or whoever you got the caps from....
