Sissy bar screws

I just purchased a sissy bar for my 07 k9. Took strut plugs out
Put sissy bar in and bolts won't thread up. Do I need longer bolts
For it? Thanks in advance!

the bolts are 1-3/4 long and I got grade 8 chrome plated. If the ends of the bar are tappered and use the collets make sure the slit in the collet is not at the thin wall of the strut.

Bingo I just got the bolts at Lowes. I didn't want to F with the set screw. I dont recall what thread pattern they are off the top of my head. I actually haven't taken my bar off since I put it on about a year ago.

I think they are 3/8'' UNC socket head set screws.
If you get them in stainless steel they look good and won't rust if leaving on your bike.

Whatever you do get Zinc coated grade 8. Stainless is pretty but strength is important there.

+1, do not use SS there was a recall on these bolts and the strut bolts due to breakage several years ago.

There should not be an issue with SS as there is no load on them. They are just retaining the rack.
USe a good anti seize on all ss bolts and you should not have any problems.

Just my 2 cents is all.

On the K9 Sissy Bar with the tappered end's. Does someone have the right size collet for these? Do you need the collets? Or would a just any Grade 8 - 3/8 x1-3/4 bolt work?

The tappered end of the sissy bar into the strut is a weird fit, not sure it appears that safe

You need the tappered collets, the collets take up tolerance differences between struts and sissy bar diameters. I had the slit in the collet to the thin wall of the strut and it cracked the strut. I cut the tappered end off (.750 or 3/4") my sissy bar and mounted it that way, the tapped hole was plenty deep enough in the sissy bar. Just make sure the diameter of the sissy bar is smaller than the hole in the strut. Mine's been like this for about 2 yrs trouble free.

I'll be honest cutting the tappered end off makes the most sense. I'm still trying to understand how the tappered sissy bar/collet system works.

Thinking out LOUD:
The struts in the sissy bar have a machined stop about mid-way through the hole. The sissy bar tappered end sits at the top of this and the slack/play due to the "tapper" is significant. I understand a bolt will hold it but why would they make it tappered? The collet makes sense except for if you put it on the tappered end of the sissy bar to take up the slack the collet can't expant. The bolt is threaded the sissy bar?

Heres a pic of the sissy bar strut hole. What is the little hole in the side of that stop ring for?

Part number bdm 240-000373-00. Biker dreams of Atlanta is where I get mine when I lose em. I have the same exact set up in my 08.

The little hole you are talking about is for the plugs that go in there when the collets and sissy bar are out. It makes sure you put the correct plug in each hole and not accidently swap it with the one from the other side. The tops of the plugs are contoured to the top roundness of the struts so it looks smooth. Once you get the plugs you will see exactly what I mean. The little holes have absolutely no function with the collets and sissy bar.

Don't cut the ends off. Buy the collets. $30 for the pair plus shipping if I remember correctly. Don't ruin the bar.
