Actually, you prolly need to enlarge the two holes (for mounting the battery cradle) in the regular rb6 chassis. In the rb6.6, they are used to mount the waterfall in the laydown gearbox position. However, the waterfall holes are just very slightly wider (or narrower... I can't remember) then the battery cradle holes.
Personally, I don't mind drilling new holes, I don't mind enlarging holes, but countersinking an enlarged hole is annoyingly difficult without a mill and a setting plate.
And of Coz, drill the two holes for the laydown gearbox itself.
