The Hurst shifter body I just pieced together has the number 0210331F on it. I bought it off ebay and the seller didn't know what it came off of. I was able to tell that it was the same as the original shifter that came with my tranny because of the position of the outside shifter plate - it looks almost like an "L" - the dodge hurst just point straight down. The original shifter didn't say hurst on it anywhere, and it had 2 springs visible from the top. The hurst shifters springs are internal.
At the same time, I bought a shifter with linkage from a dodge truck of the same vintage with an a833. Unfortuanately, the alignment and the linkage are completely different. GM didn't use hurst's linkage, and the linkage from the dodge seems of better quality (probably hurst), but you need the original linkage from the GM a833, or be prepared to custom bend your own. The dodge shifter body # is 10810211c best as I can tell - the first 3 numbers aren't stamped as hard.
