Well, here is my version of the mod...
The above picture shows the rubber pads I used to space up the middle area of the seat. They are called Grippers and I found them in the section at Lowe's where the stuff is for furniture to keep it from scratching up floors.
Here is what the package looks like...
Now, end of commercial and back to the mod pics...
Again, here are the materials used...
* #7 Rubber Stoppers
* Grippers rubber pads (self-adhesive)
* 2-M6x55 Hex Head Bolts
* 4- 1/4" fender washers above and below rubber stoppers
I thought it worked out pretty well. The only concern I have is how well the rubber Gripper pads will stay adhered. I may go back and revisit that at some point, maybe with contact cement or something, I don't know what right now.
