From what I understand, the FXDC & the FXDCI are the same bike, Super Glide Custom, as a matter of fact, I never saw FXDCI listed anywhere on the Harley site or Harleys Fitment list of bikes. For what its worth, FXDC stands for Factory Experimental Dyna Custom. I don't know where the I comes from other than seeing a couple listed on Cycletrader as FXDC/FXDCI Super Glide Custom for sale. All this being said, I'm sure no Harley expert.

Also I forgot to ask, do you have forward controls or mid controls? The top of the crash bars mount with two bolts at the top onto a mounting bracket with two holes in it where the down tubes are just below the neck. The bottom bolts to the bottom of the frame down tubes with a U bolt on each side

Those factory Harley highway bars look real nice, but I've been trying to find something in the bargain bin, just haven't found that $49.95 special yet.

I know what you mean. I found my crash bars new in the box on Craigslist for $100, they were still wrapped and never installed. It saved me $190 compared to $290 new from Harley. I try to keep an eye out for deals like that. Also found on craigslist was a quick release windshield for $100 that's about 3" shorter than my quick release touring windshield. I got that just as a backup and saved about the same dollars over new. But, this was not new like the crash bars and I had to replace two of the four 49mm clamps at a cost of about $60.00. So in the end, the deal wasn't as good as the crash bars deal.

I did see the ones on Amazon, the foot pad issue should be an easy fix. The Harley ones also use the U bolts. I couldn't tell a difference between them and the Harley brand guards. Both are 1-1/4" tubing and the only difference I could really see was the rubber footrest looked a little thicker, slightly different style, and mounted differently on the Harley brand guards. They're definitely not removable on the Harley ones, I checked on mine before I installed them.
They're a easy 10 to 12 minute install once you get started. Just a tip when you install them, don't over tighten the nuts on the U bolts, if you do the metal plate on the bars that the U bolts go through will start to bend around your round frame tubes that they rest against. I also used blue Loctite on them.
