Mine have seized on my streetfighter project and I had to hacksaw them off.

One goes through the steel linkage and attaches to underside of swinging arm and the other one is the shorter of the two which fits the cast linkage.
A spare steel linkage would be handy too as hacked a bit off mine

I have been on ebay and david silver's site but parts are not in stock.
Hopefully one of you have them knocking about, cash waiting
