Pushrod length

Can some one tell me how long the corvette style master cylinder pushrod is.
I want to make and use a temporary push rod.

With out the length I can't place the master cylinder in the correct location. Would like to make the brackets this week.

There are adjustable ones available. ABS in Orange Ca for one.

 

you would probably just better off making one , most of the hot rod parts guys like pete & jakes and CE use a 3/8" female heim end with a cut off bolt for push rod

 

3/8 doesn't seem larger enough . i can fit a 1/2" diam bolt in the piston

 

Make the bracket first & make the the pushrod to fit?
