3 speed clutch linkage on 4 speed?

So I've recently gotten myself into a manual transmission swap, I am swapping a 4 speed 64-65 a833 into my originally automatic 73 dart swinger. Since 4 speed pedals and linkages are hard to come by I was wondering if I could take the pedals and the linkages out of a old 3 speed Chrysler. I don't know the specific make and model of car but I found a couple of donors in a scrap yard that could be good donor cars.
If you guys have any input or ideas it would be greatly appreciated!
