I want to run a QTU master cylinder but my stock booster has a deep push rod the QTU takes a swallow rod. Can it be modded or another one added or will I need to find another source for a Booster.

The rod between the booster and master come as a short or long. They are cheap. Go buy the short one.

Master Power Brakes sells an adjustable rod for about $20! :thumbsup:

Where would I find a shallow poush rod? I looked all over and cant find one to save my sole.

The Master Power Brakes (other companies sell the part too) rod can to be cut to length (I had to trim mine) and then you have the ability to adjust the final length and get it just right.
