Here's what I settled on for a carrier. The black strips on it are rubber sitting in a channel, which help keeps things from sliding sometimes, and they're close enough together that things like cans in a bag don't fall through. It's adjustable about three different ways. If you see one with a sissy bar, all the ones I've seen are removable. Some stuff on the rack would cover up the stock tail light so I put on a fender and light from a '79. The seat is from an '80; it fits, and's a lot more comfortable than '81 up for long distance.
