First thing you need to do is mount the wheels, and get a good total width measurement.

Sounds like your in the ball park of width needed, but a Chevelle rear may be close too. When done you can compare wms differences to see what to do.

The 4 link is easy enough to add some metal to the frame to get it to work, and makes bagging the truck easier in 1 swoop.

A simple out rigger for the mount, and a support brace would work. For most unless your going to seriously hammer it with big hp on sticky tires. 2x3 1/8th wall would work for the outriggers, and a triangulation with 2x2 1/8th box would be fine.

With big hp the out riggers may bend, and force the frame in ways it may not like.

I did it for a kid who had a C10 which was only 2.5 maybe 3 inches at the frame. He had the mighty 4.3 Vortec V6. Which he wanted for mpg, and so he couldn't get going to fast to low. Plus it was 250 for the whole van it was in.

I don't know why my post is angry?
