I don't spend much time at all on forums anymore..
Now I remember why.
DeeW,my point to you was,if you're building the frame from scratch,
follow the basic 4" dropped axle spring on top,stamped crossmember,
cross steer,and you will have a solid chassis.
Also be sure to use tie rod ends on your tie rods,and not heim joints.
Forged steering arms. Don't fall for the cheap prices online,buy American and you will
only need to buy it once.
