These spring brackets are designed to mount onto 1967-1972 Ford F250 and half ton 2wd framesand allow you to install either 2008-16, or 2017+ Super Duty leaf springs. Pictures with measurements are included to verify fitment. The pictures here show a later truck, but the results are representative of what to expect. Please measure your truck before ordering.

Skyjacker FR173S is a 2017+ leaf option. It is fairly stout and has more load capacity than you likely need. it rides well for how stout it is. 

Skyjacker FR84S is a 2008-16 leaf option. it is plenty capable and is a little softer than FR173S. This will still have more load capacity than your frame was designed for. 
 
Both 2008-16 and 2017 Super Duty leaf springs are a massive 65" eyelet to eyelet. The main difference between the two types is the 2008 style has a 20mm forward bolt while the 2017 style has a 7/8 (really a metric equivalent) forward bolt. 
 
These brackets are often used to help lift the truck when going from 2wd to 4wd. As pictured on the tan truck, they are used with a FR173S Skyjacker 3" lift spring and without any block.
 
Every bracket uses at least one factory drilled frame hole and this makes install a lot easier. You do need to drill several 7/16" holes in your frame. The brackets work as a template for the drilling location- no guess work.

This listing includes all four brackets, enough to swap out both of your rear springs for super duty springs. 16 new 7/16" grade 8 bolts and all metal lock nuts are included.
 
Axle Perches:
All 34" wide rear frames require cutting and welding of perches to move them closer together. Perches are sold separately. 

Shocks 
with a 7" lifted 2wd, and more specifically with FR173S or FR84S and a 3" lift block, Bilstein 33-185552 should work well. Otherwise measure on your finished truck and order shocks by lenght, not by applicaiton. 
 
Supper Bracket:
This kit includes two support pieces to reinforce the frame rail to rearwrad bracket connection. 
 
You will need to separately purchase these things:
-Rear leaf springs
-Leaf Spring plate- the super duty trucks have the U bolt pointed downward but you can mount U bolts in the traditional upward fashion with a basic 3/8" thick steel plate that I sell
-Leaf Spring Shackles for rear of leaf spring (most earlier SD shackles works)
-U Bolts- upgrade to 5/8"! (see Superlift 11604 for example, but the length depends on your lift blocks)
-5/8" x 5" bolts/lock nuts and 7/8" x 5" bolts/lock nuts for 2017+ leaves 
-7/16" Drill bit
