Dual position front spring hanger

The bolt head and the perch hole are tapered. The bolt head basically sits flush with the side of the perch. When bolted to the body, the perch is against the frame. I can post a picture of it once it's off.

I'm leaning towards just drilling a hole through the frame. All it needs is a hole just slightly larger than the allen wrench. It would be the quickest solution and it wouldn't cost anything. Then I can get the complete interior in it and a full tank of gas, then tighten the bolt.
