52 olds rocket 88

I am in bad need of a master cylinder for a 52 olds rocket 88 can anyone help
Thank You.

If you dont have power brakes you can use a mastercylinder from most GMs bigger cars from around 39-54 and I think up to 1960 on the olds. I used a 53 olds mastercylinder on a 47 pontiac and they both looked identical,hope this helps. Jeff
