master cyclinder can it be moved

yes but as far as moving the push rod over to match the offset adapter, how do you do that because the pushrod is already bolted to the side of the brake pedal..?

I bought a 1/2" thick offset adapter on ebay , way cheaper than either one listed above. Was black anodized, fit perfect, but I forgot how far over it moved the cyl. tho.
You can cut and thread ur existing rod, and thread both ends , then use a 1/2'' threaded rod coupling to put it back together, adjust it to the same thickness of the adapter , to keep the stock pedal height , weld it when u have it the way u want it , and grind off (I turned mine down in a lathe), to get a bunch of the bulk off to make it look like something that belongs on a car. You will have to grind the original rod size a little to get it round enough to thread , no biggee -------
Not really enough of an angle change to worry about , mine has been on the car for a few yrs. , no problems. With raised port heads, I still had to mill the lower fin off my mopar perf. valve cover tho , to get it off.
I even had s/steel flex lines built , so I could loosen the bolts and swing the master cyl over a little if needed , but don't have to do that .
