Wilwood Master Cylinder Part #

[WE2Regal]

I want to replace the hydroboost master cylinder on my 84' with an aluminum Wilwood master cylinder. Anyone know what the correct part number is from Wilwood and whether there are any specific problems or additional parts needed?

I did and didn't see a Wilwood part number. I did see that some are using a Wilwood master cylinder over a 1" bore size. Seemed too big to me, but?? Has anyone noticed any improvement with a larger bore size?

With the one inch bore you will get a little less pedal travel likewise with a smaller one you will have more pedal travel. I have a 7/8 and it feels about the same as the 15/16 force wise but it is a lot more linear than the gm OEM replacement I had. If you plan on ever changing to a 4 disc or a big brake kit, go with the 1"
