By request, I made a short run of these adapters for you Econoline guys. This keeps the stock pedal and bushing arrangement, no cutting or drilling should be necessary. You will have to provide or lengthen your master cylinder push rod for the master cylinder you intend on using.
UPDATE AS OF 04/16/21
I am no longer going to produce these. They were always slow movers. I am trying to concentrate on other products that fit with our recent move and redirection product wise. Thank you for understanding.
