I am unable to watch the video at work... but can you let me know how many bolts hold the seat on, and can you confirm you can use the original bolts or do you need to buy longer ones.
Thank You
I just pulled out 4 of them (one of the 2 seat assemblies, each seat has 4, so 8 total) and the bolts are over 2" long apiece. Even with 3/4 inch worth of washers (or in my case, big hex nuts) that sill leaves over an inch to bolt into the floor. So no, you don't have to buy replacement bolts.
I purchased 8 big-ass (3/4") hex nuts instead of a stack of washers. Each nut cost me 79 cents, x 8 = $6.32 in parts. They just slip over the bolt acting as a spacer, just like washers would have done, but one solid piece instead. Because the nuts are stainless steel, I wanted them to blend in better, so I painted them flat black. Soon as that dries in about 15 minutes, I'll reinstall... and post how well it works.
