Hurst Comp Plus Questions

I have a Hurst Comp plus that I got with a 833 OD for my swap, but I cant find anything from the numbers that are on it. The levers a a little different from what I can see for a factory A body shifter. The Case says 285506 on, the outboard most lever has 2051 on it and the middle one has 2182 on it. The longer (inboard) lever I cant find anything on. All the holes are .500" so I know I will need bushings, or do I need the correct levers?
