This guy did do them Ted (these are for 400) but can't find them now - bought a set plus front and rear SS footrest pivot pins

It is two pins in the book my seat had one pin & a bolt fitted instead.
Part shown as no longer available but I have found a source via philward in SS I just need to confirm the length I believe it is 35 mm?

Can someone confirm the length pleas as mine is not to hand.

I found Ted that whilst some claim the pins are correct for the seat hinge bar they are in fact just the same as the rear footrest pins. As such they rattle around inside the bar and frame. I would advise measuring the hole of the seat hinge bar and see about finding some that fit, even if it's an imperial size and not metric. If for instance a 1/4" pin would be closer, then fit that, no one will know and it avoids that horrible seat flapping around when open look caused by ill fitting pins. I seem to recall doing the exact same thing, buying them claiming they were correct and then finding in fact they weren't. I may even have redrilled the hinge bar to 1/4" to allow for that size pin, simple to do, you can do the same with the frame as well, most frames seem to get damaged in that area, the tubes get a little crushed. The metal is thick enough, just fit them with some grease this time, Honda fitted them dry and that allowed the hinge bar and frame to elongate due to friction etc as it opened, plus the OE pins rusted like hell. You most likely find the holes are not circular anymore, they are oval.

Just some advice, it's your bike, do with it as you will.

Try fitting a rear footrest pin in there Ted, if it rattles around then the ones available on Ebay will do the same.
