Getting it off took a little creative effort, as one of the Allen bolts Stripped.
Remove the backing plate, left-handed drill bit and it's out. Run to my Favorite Hardware store to get a few, and missed it by 10 minutes...Closed @ 1 Christmas Eve.
No worries off to the Parts store and my Shoes didn't make it to the store... Okay now I have to wait.
But I did have time to clean it all up, and discover that the Acorn bolt that holds the front seat rail is a M6X1.0 Allen that is a direct fit.
So if you ever need an Allen for that Cylinder, you have a Spare in the Drivers or Passengers seat. Just be sure that you replace it with a bolt to stop the slide....


So now I have to wait for Wednesday Morning to get 4 new Allens, and my shoes.
