Make my own. Fit them in the car first. Transfer the stock location from the original hangers. Put the holes where I want from there. Usually moved forward a bit if they are moved at all. Along with some locations for height adjustment. Verify square and level when putting them in for final assembly.
If the results don't match the theory, change the theory.

A few things to keep in mind when setting spring-eye locations: 1. Tire clearance can be pretty tight at the front of the wheel opening. Depending on tire OD, what you're building, & whether you're open to stretching the wheelhouse, spend some quality time with a tape measure. 2. I've found A -bodies vary at the front of the wheel house from car to car, and sometimes even side to side on the same car. 3. The rear spring shackles MUST point rearward at the bottom to avoid binding the springs. If you're trying to stuff 30-31" tires into a Duster, pie-slicing the bottom of the front just forward of the flange and moving the flange forward flush with the wheelhouse can buy you that space. When it's finished off, it looks very stock. The same deal probably works on B & E bodies as well. For a drag car, I've always liked moving the rear axle forward a bit if possible...

AndyF do you run spacers also on your set up. I would rather shorten the wheel base or have the front hanger in the stock location but if you need room do what you must but don't over move it back.

I machine some 1/4" steel ones for my own car, which was way too heavy. I laser cut some 1/8" steel ones for a friends car, and doubler plates around the bolt holes. Worked out really well.
Personally, I don't see a point in going thicker than 1/8" if it's being welded in to the original rail. The factory sheet metal is going to be the weakest link.

I've had the front spring hangar moved into the sub frames on four different cars, first was a 1963 Plymouth Belevedere that we center the Mopar kit like the instruction said to do, the third one was on my1971pump gas Duster that I had the boxes moved all the way into the sub frames so the outer edge of the new boxes where welded against the outer frame rail to get as much additional clearances as I could on that car. The second car I ahd done was 1969 Dart and I had the inner edge of the boxes welded into the inner edge of the stock sub frames to get clearances between the stock gas tank and the leaf springs on the passenger side, I still had to dent the gas tank for additional clearances The last one was on my 1966 Dodge Coronet and I helped a friend, a pipe line welder move those boxes all the way in also after denting the new gas tank for spring clearances on the passenger side

And after welding the kit in I braced it with gussets.

We cut the front of the wheel well and moved it forward 2 inches. He is running 325/45 20's in the back on Foose Mags
