My centre stand is missing the ‘dog-leg’ piece that sticks out to the LH side for you to push it down with. Rather than source a different stand I was going to make up replacement piece and weld it on. Can some kind T500 owner measure there’s and provide the dimensions:
L1 - Length from the stand to the first bend.
L2 - Length of the section between the bends
L3 - Length from the second bend out to the end
If you can measure to the outside of the bend i.e. include the diameter of the bar pls. Bikes a 1970, not sure there is much difference between years, but if some can provide from a similar vintage just in case

Thanks
Adrian
