Just checking if these spring perch bushings are original. The seller says they are but I wanted to check and see if they are or not. He also says that there is no need to change the bushings. I am not sure of the condition of the bushings are in the perches and if they should be changed or not, but if they should be changed these could be potential replacements if correct. Also just confirming if the correct bolt is fine thread or coarse as I have both versions.
Thanks
