Need a fix for this:

I tried one of those plates when i had those headers, it wouldn't bolt on correctly so only used 1 bolt hole, you could make one that fits better.

I bought a 1/2" thick , offset adapter off ebay some yrs back, (was about 1/2 the going price), bolted up to the body, and took the 87 diplomat aluminum master cyl perfectly . All I had to do was make the push rod for it a 1/2" longer , works fine and looks fine----------no shield needed.
