Brake booster bolt spacing

[Chewey]

So I'm replacing my brake booster (11") and the new booster bolt holes don't align with the bolts. Looks like the spacing between the upper and lower bolts on the driver's side is about 1/4" wider than on the passenger side and the mounting holes on the old booster are the same. But the bolt holes on the new booster (Classic Industries PB7380 which is a renumbered MBM PB11007) are equally spaced. Does someone have knowledge of this or the ability to measure your bolts? Classic pushed me off to MBM who says they don't provide support to end users so I"m trying to get smart about this before having to fight with Classic about it.

If you still have the OEM unit and a want to keep all original, I would send it off and have a pro rebuilt the unit and have them re-clad the booster.  I wish I had but that time has past.

Thanks Blackbird, I didn't know that was a realistic option. I'm trying to get the car back together in the next couple of weeks or I'd look into that.
