On the advice of another member, I am reposting this here to hopefully get some input on the project.

I have an 84 FXST with a wide glide front end. I want to put a new style FLHT fairing on it. I know there are aftermarket routes I could take, but that's not what I want. I want a completely stock looking Harley fairing, and I want it permanently mounted, none of this detachable stuff.

Now, aside from the bike as it sits, I also have a complete 2012 Heritage front end, I have the take off parts from a chrome front end swap on a 2012 FLHX, hand controls, master cylinder, clutch perch, front wheel, axle, and brake calipers/lines from the same FLHX, inner and outer fairings, fairing support brackets, gauges, radios, and speakers. I essentially have probably 95% of the parts I need to figure this out, and here is my plan:

I want to take off the Wide Glide front end, install the new Heritage trees, rebuild my forks with the lower sliders from the FLHX, install the brakes and wheel from the FLHX, etc... The problem I am faced with is the spacing of the fairing and brackets on the Heritage trees. I know I can put spacers between the fairing support brackets and the trees to set up the correct spacing from left to right, but will this put the fairing too close to my gas tanks? And what about the fairing cap where the ignition switch would go? Will this be too far back to work or will I have to make brackets to move the whole thing forward? And lastly, what about height, will this sit too high to be useable?

I am hoping someone else has tried this and can offer some advice. I know I should tear into it and get it figured out myself, but I really don't want to have this thing in pieces while its still nice out. If I can hear from someone who has tried it before, and I know I can make it work fairly easily, I could do it in a weekend, but if it's going to be a lot of crazy fabrication and whatnot, I'll plan on doing it once the snow hits. Wiring up the audio and gauges will be a piece of cake, custom wiring is my forte, I just need to make sure the hardware is all going to work properly before I proceed.

One other thing I've been thinking about is the brake caliper/rotor spacing. What is the difference in widths from a Heritage to a Touring bike? I feel like I've seen Heritages with Touring fenders and wheels, am I wrong?

 

Honestly, I think you're barking up the wrong tree.

The difference in width, spacing etc. is too much. Softail's, early FL's
and FLHT's are apples & oranges.
I had purchased a late 80's/early 90's FLT batwing for my Heritage. I thought I was getting one off a 70's FL (craigslist)
It wasn't even close. Plus calipers, rotors etc. Lots of fabrication, which is ok if you have the resources for it (talent - time -- $$$$$$ - mostly $$$$$!!)

It would be MUCH easier (& cheaper) to find a nice used FLT.
You could put a Heritage front end on your FX, but the fairing is a whole 'nother can of worms. There is a company in Canada that makes brkts to att a 70's FL fairing on a Heritage. It's over $300 (Just for the brkts)
The other option (obviously) would be an aftermarket. Remember too, 1/2 the wiring harness is in an FLT fairing. It's a whole different animal.

My latest plan is to p/u a used bagger, keeping the Heritage and stripping it down to Fatboy trim. I just did a re-fi. I'll see how much $$ is in the kitty when I'm done (two bathroom remodels )

 

I like your thoughts. I have been musing along the same line; an HD fairing on the fxst would be a great look. Kind of like the Frontier that Thunder Mountain put out. I see lots of custom baggers sporting the skinny tire. No doubt some custom machined mount is needed to mate the fairing to the bike, just need the fairing to place on the bike and begin dreaming up the mounting system.

 

That's what I am thinking. I have a pretty wide selection of trees I can try out, I just need to get my bike into the shop and start tearing it down to see what I need to do.

I figure it shouldn't be much harder that making a few spacers to attach the fairing supports brackets to whatever trees I decide on. Once I get the inner fairing mounted and secure, the rest should theoretically bolt right up. I might have to make a new fairing cap to replace the FLHT one where the ignition switch goes, but that should be fairly easy to bend out of aluminum and paint. Then the only thing left is to wire up my audio and gauges/accessories, which will be no big deal.

One way or the other, this is going to get done this winter. I'll definitely take pictures and try to document the whole process the best I can.
