I’ve got sm465 and 12” McLeod clutch. Looking to replace the old clutch master and slave. Wilwood recommended the 3/4” bore master. From what I’ve read the stock master bore is 11/16”. Would there be that much if a difference and what size slave would I need? Thanks

Run what wilwood suggests. They spent the money on research and development. All you're doing is moving a clutch.

Why not keep it simple and use OEM replacement parts? I got the master, slave and hose from Rockauto. Price was pretty cheap actually and it's worked flawless for 2+ years. What year is your truck? Is this a transplant?

I have a wilwood 5/8 master in the hotrod. Works great, probably 15k miles and over 300 passes at the track.

I have Wilwood for my hydroboost brakes and was just going to match it, but leaning towards OEM. Wonder if I could put a resevoir on top of the oem master or do the have to use the hose hook up
