Really sorry I know nothing about Choppers, so please do not ask me if it fits this that or the other, I really have no clue.
As far as I am aware all these parts were left overs from restoring multiple models, so they could be a right old mix and mash up.
Seat, foams, brake calipers, brake levers, gear parts including sprocket and selector.
I have taken multiple pictures before putting all parts in a box ready for posting, so please study the pictures very closely to see what you are bidding on.
No buy it now, the auction will run to the very end to give every body the same chance.
