Subject: [6pack] .75 bore clutch?

From: James_ via 6pack <[email-masked]>
Date: Wed, 13 May 2015 12:37:36 -0700

I am planning on switching my brake fluid to silicone based. Which means I can't use my master or clutch cylinders and need to buy new ones. (Heard the seals will go bad when switching fluid types). 
I have a 1976 model that uses a .70 bore clutch slave but see there is a .75 bore. Is it better? How does it change the clutch pedal feeling? Maybe a longer pedal throw?
Advice?

James
