I am just not seeing how to remove the old assembly and install the new factory one. This sucks that I can rebuild an engine but can't do this.
PLEASE HELP!!!

I am not sure if the 92 is like the newer RK, but mine has nuts behind it - inside the rear fender.

Looking at the new one I don't see any where to bolt too. But thanks!

after taking the lens off, the may be some screws that are attached to grommets in the fender????

oops, the studs with nuts under the fender I felt are for the blinker bar. Screws for the tail light must be inside the lens as Coley said
