WTB: OMF seat latch or similar

[1989trx250r]

Hi, I am looking for an OMF seat latch in good condition. I have a seat from an 86-87 model, but am attaching to an 89 TRX. I think that i need the 86-87 OMF latch and it should attach, right? If anyone has one or something similar that they want to sell, please let me know.

Thanks,
Jason
