This is the bracket with the clutch pedals. 
The bolt pattern is different from my bracket

This Vette was an automatic from the factory.  I am converting it to a manual transmission.  One of the first steps here is to replace the automatic brake pedal with a clutch and brake pedal assembly from a manual transmission Vette.

Since the Gen V Big Blocks have no boss for the clutch pivot ball for the Z-Bar to pivot on,
I bought this bracket from Scoggin-Dickey.

Z-Bar on the bracket.

I moved the pedals to my bracket so it was a direct bolt-in.

I need to do a basic rebuild before I install this 4 speed.

This is the original bracket from my Vette. 
The bolt hole pattern matches the power brakes.

I still have to cut the hole for the clutch linkage to go through the firewall.
