The conversion makes it a weird thing. Every part of the truck has a date of mfg of 1992 on it. The VIN and title say 1993, a vin check says it’s a 93 cab n chassis. It came from the Indiana Centurion factory.
I'll drop another tid bit of history on ya, just because this information is harder and harder to recover every day.
Your VIn date and title date are different because the trucks came from Ford usually on Rail to White pigeon mi. They would get a load of crew cabs, and it could be months before they get a load of broncos. They usually took at least 6 months between rail transport and sitting in the yard until Centurion started hacking on them. So that is normal to see the different dates and seems like you have wrong parts on the wrong year.
Centurion had been doing conversions since at least the 70's. on all kinds of vehicles. There is rumors of a 79 four door bronco with Centurion stickers on the door jamb but no physical proof.
When they started making the more of the four door broncos in the mid 80s there was a lot of fighting about how it should be built. Some of you have seen the first few ugly attempts. The president of Centurion quit and started Metropolitan motors one town away in Sturgis Mi. Which of course failed in 4 years.
I always wondered if because of the relationship Centurion had with the parts suppliers it made it hard for metropolitan to get the fancy conversion stuff. They built it on as much oem stuff as they could. Using a standard bronco 3rd row seat left practically no leg room. Swing away tire carriers were also very common. It was common to see a splice in the headliner rather than a new one piece headliner.
Dick's auto parts was the main parts supplier for at least Centurion. They are just down the street in Middlebury In. Dick of course is gone but his Son Sean is running the place. They bought most of what was left after Centurion went belly up and whatever southern comfort conversions left behind at the plant. (southern comfort conversion bought Centurion) They have Centurion stuff they don't even know they have or what it is or what it fits. Molds and such.
Sean actually has an enclosed trailer built by Centurion. He was using it for his show truck for awhile, not sure now. It is the only one Centurion ever made.
Sean re produces some Centurion items, you can find him on ebay. Or give him a call.
There was an article years ago in one of the truck magazines that said the C350 was one of the best towing platforms ever produced. Something about the solid one piece body plus distance between the rear axle and the hitch made towing much more stable.
If you have ever towed much and had the opportunity to tow with one you would probably agree. It is a different feeling.
Of course that was 30 years ago.
