Looking For A Vintage, Very Elusive Part
That might be a part you get a small machine shop to make.
Does servicehonda have the individual part listed or an assembly with that part?
Try checking with Western Hills Honda in Cincinnatti. Terry in the vintage parts department may be able to help. Also, if you have a part number, any Honda dealer can do a nationwide search in a matter of seconds to see if anyone might have one. It's worked for me on a couple of hard to find parts. Best of luck!
Its possible the part is the same on other years or models. Maybe post a pic of the part to see if someone can ID it on a different year.
This is all I could come up with from the cross reference book.

Overview
77160-ML7-010 BRACKET, SEAT LOCK
This Honda 77160-ML7-010 BRACKET, SEAT LOCK is used on these models and components:
1986 VFR750F A SEAT + REAR COWL
1986 VFR750F AC SEAT + REAR COWL
I have a listing for a new one in Australia, also for used part number 77160-ML7-700.
I have no idea what the dealer would want for them if they still have them. Postage will be maybe $10 from Australia to US.
