SR400 to XT500 head compatibality Sept 21, 2016 6:51:04 GMT -5 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by headley on Sept 21, 2016 6:51:04 GMT -5 does anyone know weather a late model 2014/15 SR400 head is compatible with an early 78 model XT500. Any SR head seems impossible to get for me anyway. Any help would be greatly appreciated.
