well I found a really good deal on ebay for a pedal setup with masters forward mount. with 7/8 masters for the brakes and 3/4 for the clutch. Ya so what. But what I really found bizarre was the info I received from tilton and their form check this out.Patrick,
With your combination, we recommend a 13/16" front and a 1-1/8" rear master.
