I began installing front tubular A Arms bought on Ebay by having 2 support blocks welded into the LCA bracket. This stiffens up the stock bracket and extends the rear pick-up point about 3 1/4" to allow for the wider spacing of the tubular LCAs. LCAs installed, then the spindle, and next the UCAs. When bolted into place, even with the mounting bar pushed to its maximum inward travel, I had 3 degrees positive camber and 3 degrees negative caster. Totally bad, as I need to set -.5 deg negative camber and about 3 deg positive caster(upper ball joint aft of the lower ball joint). I compared the new tubular A Arms by laying one on top of the other and using a grease nipple in one to slip into the nipple hole of the other. The new tubular A Arms look about 1/2" to 5/8" longer than the stock arm; hence, the bad camber value. I've seen advertised, 5/8" shorter Mustang II UCAs, so here's a quick fix, but they're not available now. So I decided to make new UCA locating brackets moving the mounting points 3/4" inward. I used a piece of 3/16" thick angle iron so I could cross bolt the mounting bar with horizontal bolts and shims. The bad thing about the Mustang II UCAs is they had vertical bolts and depended on friction to hold them in place. If you got caster set, then you had to move the cross bar parallel, which would mess up your caster. I think Heidts and Bethania garage sell conversion piece to do this, but I couldn't find them on their web sites. Anyhow, I have 2 1/2" Grade 8 bolts and 2 3/8" Grade 5 bolts holding the bracket in place. If it works well, I can come back later and weld it in. If not, I can remove it and try the 5/8" shorter A Arms. My bracket also shifts the mounting bars 1/4" rearward to move the upper ball joint in this direction. I'll be re-assembling this weekend to see how things shape up.
