Hey Everyone , Im trying to fit up a rechromed rear guard to my Firebird. The original had been attacked with tin snips so I got another from what the seller thought was a 71 Triumph. It doesn't fit very well. It fouls the battery box and pushes the box to contact the frame. There was at least an 1" gap between the guard and the cross brace at the back of the tool box. Was there a difference between BSA and Triumph or are guards different from the later low frame and the high frames?. Cheers, Stu

The '71 BSA manual shows 83-3565 for the rear mudguard and the '73 T140 shows 83-4805. Presumably with the lowered seat rails the mudguard would have a larger radius.

Hey Dave, you are correct. I had another guard in the shed (forgot I had it) that I did not use as it had a crack at the back. It was from a 71 A65 and it fits spot on. When offered side by side, there is a barely perceptible increase in radius. Looks like Im welding up that one and selling the other. Cheers, Stu

I just "fit" a '71 A65 rear fender to a '72 1/2 T120V Bonneville with the lowered frame. It was a bit short and the front mount bracket would not quite reach the frame mounts. Also BSA used a welded bracket to secure the top of the fender to the frame where Triumph used a bracket that attaches to the shock mount bolts so the mounting holes in the fender don't align
