Difference in NP208 & NP241 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just came across some info that this swap might not work. I saw that NP241 on TH400s have a larger spline than those of 700R4s. So if my 241 wont mate up to the th400, can I use the parts from my NP208 that is currently on my to-be-installed 700r4 and make the 241 work? I guess my only real hangup on the 241 is that it has an elec speedo, which I would need to make it work in the truck. What would be my options if this swap doesn't work as planned? Can I use the 208? How could i make my speedo work with it?
