You did not have these bolts. As I posted above, these are new and specific for the F6B.
We have specific GL1800 bolt kits also which are a different length.
These Seat Bolt Kits are correct for the F6b, these are actually slightly longer then stock plus the tip.
I installed a set on mine with a Mustang Seat and did compare the length of the stock bolts to these replacements.
These fit fine.
