Moved? Not sure what you mean. If you get everything from the booster to the peddle, it's all there & it all mounts to your firewall. Everything else is Hydraulic brake tubing. My 1980 frame has front dis brakes, 73 may have drum brakes? If you can find a GM step-van of the 80s, check out there brake system.
I just checked my photo album, I don't have a photo of the booster mounted. I hate this new computer, I have more photos some-were but I can't find them.
It mounts to the firewall with a rod that goes through the firewall to the swinging peddle. The peddle swings off brackets under the dash. You will see that it all comes together. If the swinging paddle is not the length for you, you can lengthen or shorten that.
