63jalopy,I just put together a hybrid Camaro-S-10 and it looks like you could just switch the overdrive gears to go to a .72 OD ratio. You would need to switch both the gear on the mainshaft and the one on the countershaft. I've seen most of the gears for sale new if you have plenty of money. Might be better to find a used tranny for parts.
I took a different aproach to the speedo gear on my hyrid than Jack and put the Camaro gears on a S-10 mainshaft. Not all of these gears come off as easy as others and I had to bring some parts to a tranny shop to have them pressed off, my gear puller just would not work on one. I also found two bad countershafts when dissasembling trannys for parts. The NWC T-5 doesn't use bearing races on it's counterhshaft, so if there is any wear here your countershaft is trash. For this reason when looking for a tranny I would spin it and listen for a bearing noise in the lower part of the tranny. If you hear a noise I would consider this box for parts, not worth much more than $50.
Does anyone know if the WC t-5 fits the same as the NWC? Remember seeing a post about them being on a angle. Also anyone know if the wc box uses bearing races on the coutershaft?
