Rear Frame Crush Plates

I know this is gonna hurt, but I'll ask anyway. My Kar was in really bad shape when I got it. Long story short, needed to replace both rear frame rails. I didn't realize at the time, but the body shop that did the work did not transfer the crush tubes when they put the new frame rails in. Now here's the part that's gonna hurt. Does anyone have a spare set of these, or have the diagram of what they look like so I can fabricate? I've looked at the pics you guys have provided, and they are very helpful, but not enough for me to build them if I have to. Kar sat for many years while I built up my funds. Body shop is long gone, as are the old parts. Any help is appreciated.

Thanks Wally. I'll give him a call.
