Hi everyone, hope you all are well.
I recently picked up some like-new condition Bride Brix 2 seats with CRX seat rails already attached to them. There are 4 bolts holding the rails onto the seat, 3 of which are easy enough to remove, 1 that seems impossible.
I can actually see the bolt itself, but the rails don’t slide forward or backward enough to access it with a socket wrench (I tried a box end wrench and it definitely couldn’t fit).
It looks like the only 2 options are to either bend the seat mount bracket a bit or cut it off, so I can have better access. A 3rd option would be to hammer the rail stops down so I can slide the rails forward. Pics below for reference, but hopefully somebody who has run into this can give me some insight before I hack away at the rails.
No I won’t reuse the rails, but would want to try and keep them in good shape so I can sell them and get some of my money back.
Thanks in advance!
