Oil dipstick?

In a BB "A" body the issue is concerning where the upper bracket attaches. Original installs had special blocks that moved the motor mount forward, hence the need for a little different dipstick since the bracket attaches to a motor mount bolt. If this is not an original block and motor mounts, then one would need to search for the right one. It could be simple- maybe a standard one off a "C" body would work.
