Seat and fender options ending with a question
 

So I am in the process of making new fender struts to accomidate a rear fender that was old stock collecting rust and dust in the back of a Harley shop I like to loaf around at. The fender is the same width as stock but is too long so I am going to cut and roll the metal to shorten it. I was wondering though because the original fender struts were cut aprox four inches behind the shock mounts can I just stick a couple steel rods in the frame tubes and bracket them down? Also by the end of it I intend to throw on a 70s era jap king and queen seat,one of those big cushy duel level ones with a sissy bar to attach a gas can and a gun rack/flag pole,has anyone ever tried the k&q seat on a gz before? I did some poking around but couldn't find any info...thanks for reading and any brain jarring questions or helpful tips are greatly appreciated.

I'm not sure I follow your plan for attaching the rod as a shock support. Anything less than direct mounting to the frame will not be sufficient. If you make some sort of extension and attach them to that, the wear and tear and angular force places on that extension will most likely break it right off.

Extending the frame tubes to mount and secure the new fender should work. I would want it to be very secure and strong to support the added weight of a passenger.
As for a king/queen seat.............no idea.

The rod is a support for the rear fender not the shock,I don't think that would end well at all...Im headed to the local hardware store as soon as I find pants,wish me luck! Needs 3/4 od bar

I think it should be plenty strong if the rods are welded in,I'm pretty sure if I file the ends down a mm or so I should be able to sink them 3 inches in to the frame. Than use L bar steel to tack to the tube and drill the fender mounts in it.

What??? No Duct tape and zip ties??? :D

Well there's this cool stuff called ridiculously strong repair wrap, you dunk it in water and it sets up like a cast. I attacked the demo with a pen knife and I couldn't break it...if I can't borrow a welder than I will wrap it within a inch of its life and hit it with a rattle can

For just a fender support you'll be fine. I thought you were talking about making your own shock mounts off of an extension. Yikes.

Yeah that could be bad all around

Here's what it's looking like
