Primary oil change with extended floorboards
This is just some information.
A week ago I installed the extended floorboard kit from DK Customs. Yes I encountered the "difficult to remove" bolts as others have mentioned although apparently not as difficult as others have encountered.
This weekend I did a 3 hole oil change. I noticed the parking brake cable now runs directly under the drain plug on the primary case. There is enough slack in the cable to move it aside a bit for getting a socket on the plug for removal but not enough slack to get the cable cleanly out of the path of the draining oil. I let the oil dribble over the parking brake cable and cleaned it afterward.
