Not purchased from: Throttle Down Kustoms

I bought a 1977 Bronco with the intention of building a :NEW 1977 Bronco. The 1st thing I did was order a new chassis as a starting point. So far I have built the chassis and can say I'm impressed with the quality and fit of all the stock components. I now have basically a new 1977 Bronco chassis, running gear and it's a work of art. I used some non stock components and recommend that they make provisions for non stock steering boxes, which they have. All I can say great frame and people to deal with, Quality all the way around.
