    With the undercarriage, it pushes off the middle of the truck, and the leaf springs locates it left to right. There is much less stress on the front of the frame. The only negative I have noticed (verses a stock mount for this truck) is less ground clearance and get stuck slightly easier. Occasionally I get myself in to deep thinking the Detroit locker and power lock will get me back out.

    This is the bracket on the outside of the frame near the transmission cross member (I have tubes coming out for a step). There is a 1” bolt where the bracket and undercarriage meet and four 1/2” bolts for the bracket to the frame.

    Here the plow attaches to the undercarriage, tabs are welded on for two different width mounting patterns.

    “U” shaped strap over the top of the spring, and pins to the front of the undercarriage.

    Just for a reference pic, here is my 93 suburban I just did a SAS on using ORD brackets. You can see the front spring brackets wrap pretty much completely around the front frame horns (I'm using a late 80's ford 60 with the wider spring perches, but even ORD mounts for the narrower GM/dodge spring width's mount the same). I would imagine normal plow mounts designed for GMT400's would interfere with those for sure. The square body plow pics above look like they would work with a leaf sprung SAS'd GMT400 though.

    I would think either go 05+ superduty radius arm setup and run a standard plow setup, or go leaf sprung SAS and modify a plow to work with it

    And for reference, here is a side shot of my burb. I'm using 2" TC EZ rides front which nets right at 5" total of lift with the SAS brackets. 4" shackle flip rear with an EZ inch. Sitting on 35x12.5x17 pro comps on 17x9 rims

    I bought a 2006 superduty dually 60 the other day and ordered a radius arm kit from Ruffstuff .

    I also ordered the conversion Unit-bearings to convert to 8-on-6.5” shitty part is I will have to get 17” dually wheels to clear the superduty brakes

    Plans have sort of changed though , this thing might be giving up its 454/4L80e for another project then this body will hang out until I get the other frame prepped and ready for p-pumped 24-valve and G56 trans for use as a tow rig
