My thinking at the moment is about bending up an inch wide strip of thin stainless steel to run from left to right, beneath the rear fender 'legs' and link it up to the fender fixing screws. With a couple of extra M5 or M6 nuts & bolts (dome head socket) into the strip through the fender above the tyre area, will hopefully fortify the structure over all.They need more Poon in their Tangs. I agree with stiffening it.![]()
...Might come up with something better before winter project time, but it's my initial thought.
