Found a 73 doner, now will it work!?

I have been wanting to convert my 70 Duster 340 center console shift to a 4 speed and I happen to have just found a 73 /6 with a 4 speed. Will the belhouse, linkage, driveshaft etc. work in my car? Are all the holes there to put the pedals in? I have heard that you need to add a "hump" for the linkage but being the center console shift with a current hole will that work? Or is it just easier to cut the floor section out of the doner? (If its still good, havent looked at it yet). Also being the 340 i think i have the bigger yoke? could i just change the yoke at the end of the driveshaft to fit my 8 3/4?
