@ adamsapple you should be able to tell which one it is just from a picture on the car.

I believe my '69 big block has the original booster. The only identifying number on it is near the vacuum port. It is either 4240 or 424D. I will add pictures as soon as I figure out how.

The MBM booster is a Delco reproduction....I've been told that it is a GM authorized replacement for the Bendix style booster originally fitted to some cars but I have no data on what years of corvette had the Bendix. Where is the incompatibility? Is there a gap or space between the new boosters push rod and the plunger on the MC? If this is the case and you were to order a new deep hole corvette style reproduction MC they will come with an adapter to fill that gap. Its about a 1" long round steel plug with a machined recess on one end (to fit the booster rod in to). The MC is designed for power and manual brakes. You use the spacer for power...no spacer for manual. I sell these parts but have not tackled the booster install on a corvette....yet. Will be converting to power brakes in the near future. Dave

the bolt spacing for the master cylinder was wrong. I would up getting a rebuilt original.
here is my latest update with very little progress this year. I did remodel and expand my house and my side business made twice as much money in 2013 as it did in 2012. This left little time for the corvette.

Looks like you finally got the correct booster...waHOO!
It's getting closer Ben...a little at a time.
