Finally a bit of progress. I removed the old 7 1/4" rearend and stripped down my 8 3/4 to a bare housing. I've decided to stick with the torque arm idea and build my own rear suspension. The center bracket for the rearend housing is from Currie Enterprises and is designed to work with a custom build torque arm from Spohn. I'll be building my own cross member for the arm similar to the one pictured. This is gonna take a bit of fabricating. Other parts I finally received are some Welderseries axle brackets and bushed rod ends. The back brace is a Moser part from summit, RMS leaf spring boxes, some FFI 11/16" tie rods, and my finished 16:1 fast ratio steering box.
