I am looking closely at the possibility of doing this with a GM nv4500, 2WD. The reluctor wheel for the vss is fairly large and (in my opinion) rather over built for the sole purpose of a reluctor.
I am looking at using a speedo gear set from an SM465 and modifying the tail housing on the nv45 to accept the set. The geometry looks possible but I'm uncertain if the beefy reluctor wheel serves any purpose more than holding the reluctor teeth. For example, it looks like it might be built to reinforce the output shaft in which case I may not want to cut the reluctor wheel or turn it down to the necessary diameter.
I believe the dodge gas version had no reluctor wheel and it seems to be preferred so I'm assuming that the Dodge version shaft diameter is fine without the beefy, pressed on reluctor wheel that GM uses.
If those assumptions are correct then I can cut the reluctor wheel sleeve where the teeth are and insert a speedometer drive gear set.
That all assumes that the reluctor wheel is NOT designed with the intention of providing additional support to the output shaft. I really do know if it can be cut without sacrificing the strength of the output.
