I am putting the exhaust system in my 52 F-1 chassis and do not have a rear bumper or brackets yet. Could anyone give me the vertical distance from the bottom of the rear frame rail to the bottom of the stock bumper where I can determine the distance of the tail pipe to the bottom of the bumper. I hate to get it all installed and it not clear the rear bumper.
Thanks,
Bill

 

I'd do the bumper first.

 

This is a 48 Panel they came standard with a bumper, most other trucks didn't have one stock - I can only get you close
