GM Brake Cylinder Upgrade???

I remember guys doing this upgrade but I can't find the thread with the part numbers in it. Seems like it's an 80's-90's era Ton GM piston that they were using.



Can anyone help me out on this?? I'll be getting them from NAPA and the thread I looked at had napa part numbers listed... I just can't seem to find it.

Thanks... .



For anyone else that checks this out, The ones I used were 94-95 model cylinders that take you from 1-1/16 Diameter to 1-3/16 Diameter.



The funny part is that I threw out the boxews with the part numbers before I could post it on here.

or ask for the 3500 or 1 ton wheel cylinders

Mishkaya's number is the same as what I got.

I hope it makes a noticable difference.



I had a hub seal die which cooked my already poor acting brake pads on the driver side. . I replaced the bearings, races, wheel cylinders and now the pads today along with a new PML cover and synthetic fluid. It's been a very expensive weekend.
