Source for exhaust bolt nuts?

[W1BV]

Seeking an extra, or two, nut that fits the bolts that the pipes mount on. Or does anyone know the size so I might find a replacement?

EDIT: Found a source...https://www.partzilla.com/product/yamaha/90179-08004-00

Thanks!

someone correct me if I'm wrong but I believe the nuts are 8mm-1.25 and the studs are 40mm long. I bought mine on ebay for $13. I've got an 80 midnight special. it makes sense that they wouldn't differ from model to model but its possible.

I've bought lots of them from Partzilla.
