I put discs on my 68 442. The donor car was a 1973 Omega. I don't know what made me choose this master cylinder in 2005. Can you see any reason this MC would not function correctly on my car?

I'm just wondering what booster you might be running and is it for an Omega or Cutlass. The MC numbers for a 68 or 70 Cutlass (I checked both) aren't the same as yours. The Omega looks like it runs a different booster than the cutlass/442 too (I'm assuming you have power brakes). I would assume the brake actuator rod might be a different length for the Omega

 

Yes, power brakes. This was the booster that was on my car when I purchased it. I sent it to Brakeboosters.com for a rebuild and polish back in 2003. I just spoke to the guy and he says he always returns the booster sent to him. If in fact he sent me what I sent him, I should be allright. How does a 1" vs 1.125" bore on a master cylinder effect things?
