Anyone used Proform's 950 CFM #67108C replacement main body? I have a billet 1.75" baseplate and can probably piece together another carb w/ a few other items w/ replacement main body.

Also, any idea what the difference is between the 67108C "950" and 67107C "850" bodies that both use the 1.75" throttle plates? I can't find anything other than jetting specs to see where differences are between the two.
