Clutch slave sizes

[GuyWeller@aol.com]

Can someone confirm the Internal Diameter of the correct clutch slave cylinder
for a '71 Sprite?
The one on my car is 7/8" , but all 4 of the parts suppliers I have tried for
new seal sets insist on supplying 1" diameter.
I finally obtained a 1" diameter cylinder at an autojumble (50 pence) so I
plan to use that.
Logic tells me that if everything else is the same it should give me a lighter
clutch, but more pedal travel to disengage.
