The G80CS and G15CS are the same footpegs. The big casting is specifically for the AMC heavyweight frame (which includes the N15). Prior to '64 or '65, the footpeg was fixed. from about '65-on, the folding footpeg was standard for Scramblers.
My G80CS has fixed footrests, which mount identically as my G15CS with folding pegs (yes, the G15-style footrests can be mounted on an earlier bike, but the fixed pegs can not be modified to look like the later ones)
My G15CS has the folding pegs
My Ranger has different mounts, but the folding footpeg part is the same part as the G15.
No, they did not come with rubbers, but one can retrofit almost any rubber (When I got my G15, the rubbers said 'Ducati')
