These have been on a GN that has been stored for 8 years.
One spare wheel has never been used.
Tires are BGF's are 245/50 ZR 16.
All 5 will go for $900.
I think there is a stock piston in the original box which has been around for at least 25 years?
if you have not located a piston, let me know and will look for it.
