My 87 didn't have it, but that truck was so rusty when given to me(think I started a thread titled "My First Ranger") I plum tossed it and drove around without one for 6 or 8 months. One day I saw an ad in Thrifty Nickel for a 91 tailgate- $50. It was near where I went to church there and made arrangements to go see it that weekend.
It was still new in the box, had everything attached and ready to go. Wasn't sure that it would work but I told him if it did I'd buy it.
That thing slipped right on and latched right in. I paid him $50(it might have been 75)and we stood there and talked a bit
He'd had a Ranger but had sold it not long after getting rear ended a bit, and the Insurance had sent him a new one that arrived after it was gone. The guy said he'd gotten tired of it sitting in his closet.
He showed me the invoice that came with it, the total was about $1100.00, and included all the latches and hardware, ready to install.
It had that silver plate, and made my rusty ol 87 look gobbs better! Hek, I liked it just fine
Here's that thread I wrote about it
