AJ or Ewill3rd- can the case extension be swapped in place from a 95-96 transmission? I haven't yet priced these parts but I'm assuming they won't be cheap. If they fit from the older transmissions, It'll be a cheap fix for me and it will make some scrap aluminum transmissions worth more than $0.60/per lb.
