C1 master cylinder application

[Thomas H.]

I came across a master cylinder with the following numbers:

Casting 5456022 - small 022

End cap number - 5456446, 320-R

Can anyone tell me the application of this master cylinder? I suspect it is not Corvette since it has threaded mounting holes.

Thanks,

Tom

Not Corvette as you have surmised. The 320-G is what you are looking for. The 320-H and 320-F are Buick parts. Same casting numbers as Corvette but not configured the same and, of course, the end plug has the H or F. Never seen an R.

Troy,

Thanks for the info. I figured it wasn't Corvette as soon as I saw the threaded mounting holes. I'll have to double check that "R", my eyes may be playing tricks on me and it could be an "F".
