I double checked, and I got the elevator bolts at Lowes. Go on their website and search "elevator bolts". They are black which worked well to blend in with the black mat.
Had this on my mind and went down to a Rural King that just opened up not far from me. They had two of those 6ft stall mats that were ripped up a bit. Got them both for $15. Thanks for the idea!
I have a L3700 SU. Pretty basic tractor. I took the floor boards and step off and had them Linexed ( truck spray bed liner material ) I think he charged me 60.00 +\-. If is now almost 5 years old and looks as good as day 1.
