Does anyone know the size of the bolts that screw into the frame on either side of a solo seat above the oil tank? I just pulled plastic plugs out of mine and want to go solo, the diameter of the threading looks fairly large, about 1/2".

 

1/2 x 5/8. Threads are 13. J&P has them for $7.99 but you can find them at the HD dealers. I have an 05 FXSTBI but they did not come up on their computer. Luckily a guy working there said they have them for a Road King or Fat Boy.

 

Thanks Danny, I really appreciate the info.
