Changing rear rotor on 91 softail anyone know the bolt size

 

I want to say they are 3/8x16.


FWIW the bolts cost 99 cents each at your local dealership.

 

Thanks I will look at dealership seems like everything I try to buy they have to order I am almost sure they are 3/8 16 but not sure on lenght

 

I think they are 1.5" long.
If you have a paper parts manual it will tell you the thread size and length of every bolt and the size of every washer on your bike.

 

They are: "#4726 BOLT, 7/16-20 X 1-1/2 hex. hd. (Grade 5 steel)" and list price is just over a dollar each.

 

I went to Harley shop today they couldn't find them in their computer or should I say their computer couldn't pull them up,they have tapered head and are Allen head

 

Are you sure you aren't talking about the pulley bolts??
They are slightly larger than the rotor bolts.

 

Man I'm sorry I screwed up.
Are you running a mag or a spoke wheel?
The bolt size I gave you above is for a mag wheel.
The spoke wheel uses
3655A SCREW 5/16-18 X 7/8 TORX pan hd with a lock nut behind it.

 

Soliud rear wheel don't see any way to put bolts on guess I will pull bolts and go to hardware store and match them up,was trying to get everything before I start

 

These are the bolts you need for a mag wheel
