hello, I have a 71 Bonneville, sump plug filter is dripping oil looks like the threads are pretty well knackered anyone had to repair how did you go about it and I'm looking for a rear light bracket the pressed steel one, I have been told there are 3 different lengths its a built in 71 and registered in 73 so don't know which one it is but found a new one on the net £60 + the dreaded fell of the chair
