I have a 65 f100 with drum brakes, no power anything, 3 on the tree, 352 and yesterday I was given a 79 f250 , 460, auto, power everthing. Should I swap parts to my f100 like the driving gear and brakes or is it a big deal to swap the cabs? Any help on this would be appreciated. Thanks!

 

You can swap your 65 over to the neweer chassis but you have to relocate the rear cab mounts. There's a thread further down the list with a link detailing a similar swap.
