just did this
measure from the bend to the short end... should be 2 inches.
Then measure 12.5 inches to the inboard tip (with the 1/4 inch radius)
Measure from the new cut short end (that's two inches from the inner portion of the bend) inboard 6.5 inches and then draw your lines to the tangent at the 1/4 inch radius
Your spacers will rest pretty close to flush with the outboard edge of the lower bulkhead, NOT FLUSH--but centered on the bolt hole that will be drilled through it.
Make sense? So essentially you'll be cutting about an eighth off of each end. My advice is to wait to cut your tapered angles for the 605-c's. Cut those after you've drilled the holes so that you can preserve edge distance at the radius. If the doublers are just a hair off, you'll lose that in a hurry, but with the extra space to work with you have all the room in the world
