It’s mounted to the subframe on double shear tabs with 5/8 hitch pins.That mount looks good! I can't really tell how it's attached to your subframe, though (just curious).
What's that (i think..) magnetic angle holder thingy you got there on the shop floor?
And the magnet is an adjustable angle welding magnet. It’s great for holding things in position for mock-up. I have a dozen in various sizes.
