Hey, since owning my 1990 GSPD, 14 yrs. I've replaced the seat lock twice because of the plastic housing failing - cracking and taking too much stress. In trying to mount a new-to-me Corbin, today, I noticed my latest lock housing is failing, as well. Looking up the part # on Bob's BMW site it looks as if a new lock set runs $55 !! Has anyone else had their locks/housings fail and, if so, have you come up with anything that won't fail? I'm not so concerned about locking the seat, more interested in having the tongue, attached to the seat, be accepted in the lock and keeping the seat secure. It seems that the lock system is the only way to ensure the seat won't come off Any help, creative solutions, pics, would be appreciated.
