"Standard Chinese gearbox - nothing special. Uses 8mm bushings/bearings (not included, neither are screws). I would highly suggest radiusing the front corners of the cylinder opening. I've seen two version 6 gearboxes crack at the front so far (possibly just from age or lemons/poor QC, but better safe than sorry). Decent price for what you get - V6 shells can be a bit hard to find. If you want to use a regular V2/3 gearset, go for the CYMA gearbox as it has the elongated bushings which can be rotated to use either V6 or V2/3 gearsets depending on the orientation. For those who don't know, the Version 6 gearbox uses a spur gear (the flat one) that is smaller than a V2/3 spur gear.

"Bought this to house my Siegetek 20:1 DSG because of CYMA's P90 Quality Control. My stock gearbox has waves in the rails for the piston and needs like 40 (exaggeration) shims to take up the space between gears.
However, this won't work with that gear set because the 20:1 ratio takes advantage of the version 6 oblong bushings and need to be reversed. It will only allow stock sized gears to mesh.
That being said, another review says this takes 7mm bushings, however I used 8mm bearings in a different Indoor setup instead, and they fit like bearings should.

"I recently purchased this shell and a motor mount to refurbish a used P90. The shell doesn't come with any paperwork, so I had no idea what size bushings it took. I used some 7mm steel bushings I purchased to see if they fit and they slid right in with no problem.

Definitely a good buy for my rebuild.
