Honestly, the adjustable arms and ELBJs aren't really super relevant. The first "fit" of this setup on this car in this thread as on all stock and original arms and balljoints. It was still obscene.

I'm off work at 6pm EST today, HF is about 8 miles away, so it'll take me anywhere from 10 to 80 minutes to get there. I hope to be back home with said jack by 10pm EST.

A nominal 10" wheel should be 254mm
Your wheel is 280.5 outer dimension
Lip flanges are roughly 13.25mm
Backspace(164mm) - half the wheel(140.25) is 23.75. This is the correct math of an un-named industry metric. lol
Subtract the 13.25mm lip flange that exists in reality but is not accounted for on paper = 10.5mm offset.
Edit: Nope. This is wrong. Fake News. You can disregard the rim flange thickness. Don't believe the internet

280mm OAH = 140mm to center of wheel
164mm measured from outer edge to hub pad - 140mm to center of wheel = +24mm offset
or
254mm known wheel width, half is 127mm
164mm measured outer edge to hub pad, subtract ~13mm for lip flange = 151mm from tire bead to hub flange
151mm to hub flange - 127mm to center of wheel = +24mm offset

Offset is calculated to the center of bead to bead distance, not outer edge of wheel. So remove the rear lip flange width from the backspace before you calculate offset.

I still think you have 15x10 +10, nominal, wheels.
This is why there are arguments over which measurement method is better. There is no industry standard, min or max, on the thickness of a wheel's rim. Truck wheels often have a standard inner rim profile/thickness and a 20mm fake beadlock on the outside.

If people that work in the industry don't agree on how to measure wheels, then how am i supposed to determine what to order, or how to determine if what i have is what i ordered?
