Look for a donor truck with disc brake front end locking hubs and a 205 t-case. Their were tons of them built that way and with the 205 it will bolt where 203 went all that might be needed is a shorter rear drive shaft unless the donor truck is the same wheel base than use the rear drive shaft too. The 205 is one the strongest and lowest maintance t-case ever built.

Look underneath your truck, if you have a short (like 8") driveshaft connecting to one longer one, you just have to remove that short one to put in the NP205. I'm not sure that all trucks are this way, I've only ever seen one truck like this, all the rest had 2 basically equal length driveshafts. If you have either one or two basically equal length you'll need to have the shaft shortened and balanced.
Basically everything will swap over, if you score a donor truck, just take the driveshaft (s) from it.

Chevys are much easier to find around here than the correct year ford. The only place i found the ford parts wanted $100 for each spindle. So I just went to ecology and got the chevy ones for $10 each. I wanted to keep it all Ford but I couldnt find any 4x4's in the junkyards. So if you can find the Ford stuff for a good price then use it.

Thanks for all your help guys. I have got me a 1977 Ford F150 donor truck with manual lock outs. It is complete with everything. The axle codes and transmission codes match the ones on my truck, so I am amsuming that it is all the same gears. My only concern is that if one of the previous owners did any gear swapping. I read somewhere, but can't find it now on how to tell what the ratio is by turnig the tires and counting the revs of the drive shaft or vice versa. Can anyone help me get an idea of how to check this out for sure. Also will the power stearing gear box bolt right to my 74 just like it is on the 77? Thanks in advance.

Yea, the power steering will swap in 4x4s from 67-79.
Jack up one side and turn the tire by hand and count the revolutions of the driveshaft. Ten revolutions of the tire should give you an accurate ratio, 30 turns of the driveshaft is 3.00:1, 35 turns... you get the picture. Make a white mark on the driveshaft to make counting easier. A limited slip will not allow you to perform this test, you'll need to look for an axle tag for verification.
