@sbelinge - before you decide to build a bracket, you should disconnect the LSPV anchor from the rear axle housing and zip tie the long spring to the top of the body. If your braking is improved, then you'll know you need a bracket.
This bracket raises my LSPV anchor up by 3.5", which is around the total lift I got after installing the OME and larger tires:
Just go to Parkrose Hardware and have them cut a 6" long 3" wide 1/4" thick steel bar. Also, bring the original anchor bolts with you so you can buy a pair of duplicate metric bolts along with nuts and lock washers.
Next you'll need need to disconnect the anchor from the spring so you can measure the offset bolt holes. When I did this, I made a pattern from some old cardboard and an exacto knife/marker. Get the new holes lined up so they mirror each other, secure the steel bar to a 2x4, and drill out the new holes. My holes weren't perfect, but they didn't really need to be.
Last step before reassembly is to bend the ends of the bar into 1.25" flaps which is pretty easy to do with a bench vise and a 5# sledge. After you have two 90* bends and you've done a fitment test, it would a good idea to apply a coat of rustoleum to ward off corrosion (I wish I had done this btw).
EDIT: Consider buying some redundant 7" and 8" long pieces of steel bar from PH just in case you need more length or if you make a mistake along the way...
