are these rails required for installation of the seat on a 99 drifter 1500
The left one is needed as the nut that holds the rear of the two-up seat fastens to it. The right 'rail' is the grab rail that is up behind the seat and I took it off long ago with no ill effect.

Thanks
The left one is definitely required. It is actually the structural element that supports the seat. The right one is the grab rail, but isn't required.
Chief,
I beg to differ, having just reinstalled my grab rail. Using his picture, right-reading, the right one supports only one thing: a scared rider's hands.

Meant my other LEFT... yeah the bottom/right one is the grab rail and isn't required.
