8BA rod bushings

[russcc]

Any one know of source for undersize r8BA od bushings. By undersize, I mean the ID of the bushing itself. I understand that the OD comes in 3 or so oversizes, but the ID is usually real close to .750 so it can just be honed.
I would like the option of being able to have them bored so I get an exact 7.000, OAL, or whatever I need for the engine assembly to get the pistons the same distance in relationship to the deck surface. Also, does the Tobin Arp or Sunnedn rod machines have the capability to adjust the OAL of the rod during machining. Thank you Fordbarners.
