Fabricating new front uprights for the modified Manta front suspension

[Blueovalz]

I agree with the weight thing. My rear uprights are all sheet steel (.090 and .120), and they are within 1.5 lbs of some cast aluminum ones typical of that era. The entire reason for this front upright endeavor above was to have better flexibility on bearings and steering arm geometry, which will still need to be developed. My greatest angst was welding the bearing cups to the arms, and having them shrink so tight that I, 1) couldn't press the bearings into the cup without galling both, or 2) that when successfully inserted, the bearing stiction increased so much, I was't sure I was benefiting from the process.
