Too bad they got rid of the best part of it- the original drive train. Years ago I had a customer who loved old stuff. Somehow, he found an old Triboro Bridge and Tunnel Authority Power Wagon from the late sixties or the early seventies. It was used a a pusher to move disabled vehicles. It had a slant six for power, and Dana 70 axles front and rear, with enclosed u-joints on the front. I don't know what ratios it had, but top speed was around 50 MPH. At some point he scrapped it. Too bad, it was the only one I'd ever seen. It would probably be collectible today.
