Save me a search- wheredja ged 'em?
Bought and sold so many things from OzSTOC members and others through the Forum, Gumtree, eBay and Facbook Market Place, don't remember now.
But my best recollection, I got 'em from an OzSTOC member who listed 'em on Gumtree, and I'm guessing he was in WA. Probably doesn't matter, they were a custom made job, CNC machined from a solid block of alloy, and whilst they are a very professional looking piece of gear, the holes and threads don't exactly line-up precisely and fitting needed a little bit of force.
When I give up the ST, I'll consider removing some of the extras, eg. Russell Day Long saddle, the Delkevic pipes and these footboards, and making them available to Forum members. Duncan has already put his hand up for the pipes, so he'll have the right of first refusal. Likewise for you (if you're interested) for the footboards, ie. if you don't give up the ST before me.
