The Jardine Passenger Backrest
Here's an older picture of the Jardine Tall Passenger Backrest. I installed (notice the stock seat and tail light). It's very comfortable for my wife, as she'll set back there and SLEEP!! My only complaint about the backrest is I wish they would supply the correct bolts for it. Jardine outlines in the instructions to reuse the stock fender rail bolts to attach it, but they're toooooo short. A call to Jardine netted a package about a month later with 4 more incorrect bolts. They insisted that I must be trying to install it in the wrong place... Otherwise, I really like the backrest. The chrome is beautiful and scratch-free, and hard as nails. If you buy one, go ahead and pick up 4 bolts about 1/2" longer than the stock bolts that Jardine recommends to secure it with.
Here's a newer picture, and you'll notice that I added a Mustang concho to the rear of the backrest pad to match those on the seat. I just can't help myself, doctor!
