Best man I know that could possibly answer that question would be Wild & Free... Sorry I'm not much of a transmission guy...

measure the input shaft, pretty sure both are 1 1/4"

If it an nv4500 you could do a swap, just make sure it doen't have a counterbalance weight inside the tail shaft and make sure the shafts are the same. Some GM applications add a counterbalance weight inside the tailshaft of the tranny, I am not sure if the Mopar gassers had one or not, I don't think they do but make sure and check. If it in there you will need to remove it"Its pressed onto the output shaft and can be a bugger to get out". If you put a tranny behind a GM diesel without the weight it will break the crankshaft, I have seen it happen. What is wrong with the NV4500? any do it yourselfer can rebuild them with ease and parts are fairly cheap and common.
