GMC Astro Help Needed

[Day 2 Muscle]

I've been working on this for what seems like forever and never noticed that the cab hinge arms are missing!! Bought second hand.. So can anyone help me with some basic measurements for these arms? How tall, at what angle are they? Maybe a good picture? I will have to scratch them but the measurements will make it easier. Thanks

The rise up .275" above the top edge of the frame rail, are .050" thick, the hole diameter measures .080", and measure .125" wide at the bend.

Where each arm meets the frame rail, they measure .200" wide (as in front to rear width, along the length of the framerail), and at the end of each arm where the hole is, they measure .140" wide (or diameter, since that part is circular). Hopefully you can see in the pics below that the outer face/side of the arms is flush with the outer face of the framerails, too.

When making new mounts bear in mind out of the box the the cab sits far to high something like 3/16 ".

Thanks Mark. I've been following your build, I noticed you changed front wheels, did that move them out?
