Harley Oem floating rotors
Hello all, maybe someone can help me out I’ve got a 2007 fltr I have a couple new old stock floating rotors both have 2 3/16” centers and are 11 1/2” diameter one is 6mm I’m hoping to use it on my rear Harley part number 44362-00 wondering if that part number is preceding the 44357-00a new part number. I also have a nos 44364-00 it’s 5mm hoping to use it on the front and wondering if that part is proceeding 44358-00a if so ill pick up another 44358-00a and have new rotors all the way around my fronts are shot. I’ve done all the research i can and can’t find the answer a Harley parts guy told me he thinks they are for a softail deuce but these parts are from before his time at Harley. I tried reverse matching them and it seems like possibly the new rotor part numbers fit the deuce and ‘07 fltr but I would like to be a little more sure before I put them on. Thank you for any info I can get I would really like to use these they are brand new old stock nice parts. Trying to get the bike ready for the season.

Does the 6mm (I assume thickness?) have 3/8" bolt holes (rear)? and the 5mm have 5/16" bolt holes (front)? ... Then that should do it
Btw, nothing unique about the Deuce. It would have used the same OE rotors as your FLTR except of course you would use one more up front

Thanks to both of you yes the 6mm thick rotor 44362-00 does have 3/8” holes I forgot to mention that. between that and it being 6mm thick I figured it would work for the rear. the 5mm thick 44364-00 has 5/16” holes so figured it would work for the front. I just have to buy one more 44358-00a now and I’ll have some really nice rotors all the way around. The Harley parts guy tried talking me out of it because he thought the rotors were different for the deuce but it looks like they take the same rotors as the touring bikes they just have a spacer as well. It is going to be really nice to have new brakes just put new pads on my tired rotors end of last season. all well new pads are pretty cheap. Bought the pair of nos rotors for 80$ so I can’t complain. Thanks again.
