Will - I don't know if you've got something similar on your 'bird, but if you've got a Nova reverser I think you probably will. There is a plate attached to the front surface of the reverser box (one corner of the triangle) connected to the plate are 2 arms each end of which is bolted to the chassis (corners 2 &3), each chassis end is connected by the third bar.
You can inspect from below or with the tunnel top off. My breakage wasn't obviously apparent until I put my reverser box back in and tightened the nuts.
I've just taken this mounting out tonight - looks like it's been repaired at least twice before -I'm definitely getting a new beefy one.
I'm not sure if there's time for a bulk buy as I want to get mine back on the road ASAP. I'll mention it to Bruce if there's any more interest.
Cheers
Rob
Edited to add - I can email photos if it helps
