Moser 12 Bolts

[pat123]

Hey guys
Iv got a question about mosers 12 bolts and brake compatibility. Iv tryed to contact them but am still waiting so i figured it cant hert to see what you guys have to say.
So im looking at a Moser 12 Bolt with Ford style pressed bearings. Im also looking at these 2 rear brake kits. Wilwood (140-11394-DR) and Baer (SS4). In Wilwoods rear flange sheet iv figured its the "Chevy Special" bolt pattern but my question is what is the axle offset? Im pretty sure mosers axle tubes are 3"O.D. but the offset im unsure of. I see the most common offset Wilwood has is either 2.81 or 2.91. Is that a custom thing i can order from Moser? And the Baer i cant seem to find any of that info.
Last off what are some pros and cons to either Baer or Wilwoods systems?
Im planning on running a 15" rim.
Thanks Guys
Pat
