Looks sturdy
This is what I was thinking. The whole set up is already heavy enough without adding more weight for something that could be done with less. Someone on here has one made with square tube and I think that's what I'm leaning towards.Thick flat bar can work if it's braced correctly, it just typically weighs a lot more to make it strong enough vs tubing.
For measuring purposes would a 2x4 block be about the same as new body mounts and 1” pucks? I want to see if that’ll be enough lift.
I removed the body mounts completely and set it on 2x4’s at the corners. Best I could get the angle was 7 degrees.I would slide 1.25" pieces of wood between the existing body mount and the body. I'm not sure about K5's but the K10's have body mounts that vary in height.
The doubler adapter is from Jed’s Machining. I’m not familiar with the early ORD ones. Now that I have to cut the floor no matter what I’ll probably just rotate the 205 back up. Then everything is parallel again and the ground clearance is 100%Imo, the hardware being at an angle vs the straight crossmember will be a problem. Even if you make spacers to go between the adapter and crossmember the sleeves inside the mounting bushings plus the surface of the crossmember itself where the bolt head sits will resist the angle and want to be straight. I'd bet you'll be plagued with broken bolts.
How did you rotate the 205?
That looks like an early gen 1 ORD Doubler steel adapter, I'd rework the mounting foot so it's parallel to the crossmember.
The adapter is drilled with two different mounting options. The first one is up 2 degrees so the 205 is basically flat across as well as the mounting foot.How did you rotate the 205?
