Clutch Master Cylinder/Slave Cylinder Question

[coolfool_2]

I recently swapped my 61 front crossmember with a 1986 c10. As a result, i had to come up with a new setup for the clutch/brake system. I bought a Wilwood 260-1304 clutch master cylinder, thinking it would work as I have seen other members using this setup. I got it installed but it doesnt seem to be throwing the slave far enough. To get the clutch to engage, i had to adjust the clutch fork so far out that while it will fall into gear, the clutch slips so bad that its undrivable. Am i missing something in tuning this setup to work with my 61 or am i going to have to find another master cylinder with a larger bore? Really confused on what I am missing as i thought this was a recommended combination for the hydraulic clutch.
Thanks in advance.
