BW velvet drives to crash box's??
 

im having some problems with my velvet drives, so in the mean time i was gona throw a set of box's in i have access to, but my question is the box's have the 4 bolt flange on the back of them, how do i convert them for tail stock off my velvet drives to work?? any help is still help !!! thanks a ton.....

I kind of remember seeing some custom tailstocks for the old Daytona box back in the day. But other then that there is really no way to do it.
