Working on some new cab mounts and crossmembers for the suburban. Nice to be able to 3d print them to confirm geometry without wasting steel.

Finally got the 73 Ford running well. Dug into the carb to find it full of sandblast sand from the previous owners frame restoration. Swapped out the old 750cfm summit carb for a fresh 600cfm. Added a 10 micron fuel filter to keep any remaining debris out. Little bit of tweaking to the tune and it will be running like a top. Next up alignment and get the tires swapped onto the correct Ford wheels.
