Found these on Ebay:

This one is a 75, but a 1" bore:
eBay Motors: Tilton 75 series 1 inch Master Cylinder NASCAR (item 180077985070 end time Jan-29-07 20:09:34 PST)

This one is a 15/16":

eBay Motors: Tilton 15/16 master cylinder IMCA nascar sprint race (item 200071629833 end time Jan-28-07 18:35:46 PST)

This one is a 1" bore:

eBay Motors: Tilton 1" bore master cylinder Imca nascar sprint (item 200071629462 end time Jan-28-07 18:34:35 PST)

The last two are at $9.99 with 4 days left. The first is $39. I bet you could get one or all for less than one retail. There were a couple of pedal assemblies with master cylinders that were pretty cheap as well. One might be the right size.
LOOK BEFORE YOU LEAP!!!!
