(even) more 3/4 ton prep (P.2)

​Got my rear diff cover the other day. OEM Ford piece ('08 Superduty), same one I run on my F250:

​Degreased it, then shot it with some clear so it wont corrode. Did the same on the cover on my F250, and that's looking good years later.
Also, more parts!

​These are B-Code Superduty leafs, that I picked up off an old friend Saturday.
So I did some research on these things, this is what I came up with:

Ford Bronco 78-84 1390 5 leaf
Ford Bronco 79-93 1650 (202/276) 4+1 leaf
Ford Bronco 94-96 1650 (230) 4+1 leaf
Superduty:
B code 98-04 2998 (320/670)
C code 98-04 3626 (350/730) - dually
F code 98-04 2695 (334/776)

What does all that mean? 1650 is the spring load for a 96. 230# is the deflection, which is ore or less how 'stiff' the spring is. The B code leaf has a load of 2998 (with the overload) meaning it can carry ~1300# more than a stock bronco leaf. But, the deflection is only 90# higher w/o the overload. The second # (670) is the deflection with the overload, which I am not currently planning on running. So it should be a touch stiffer than stock but not by a whole lot. My guess is, adding an AAL to the original bronco leafs, or whatever else I need to do to raise the rear 2", will probably make the spring pack stiffer than the B Codes. So hopefully this works out, but I wont know for a while yet. My current plan is to strip & rebuild the front end and then drop the motor in, to see what ride height looks like. Then after all that is done, ill tear into the rear end and get the axle & springs swapped.
