309 masters on ebay

[detfox]

The original 1969's are 7/8"  and the carsflash master is 1 3/8"

I got lucky, the one I purchased measured at 7/8" I feel better - Thanks for the info.

yes it may measure 7/8  however most likely the front thumb pad was redrilled and the U S restamped. that being said much better then a repop   I M O . good luck

Hmmm I bought one too, haven't arrived here in the Philippines yet.
So Carflash masters are larger bore, will that not affect braking performance?
Or are they sleeved to same bore as the original 69 master cylinders, I hope so.
