After a lot of test-fitting this what I ended up with remaining from the original TTB crossmember. Looking back now I could probably have saved a little more of it.
I have the radius arms built and did a bunch of plating on the beams, in addition to welding in the uniballs.
Crossmember is fully welded in now too and the steering box has a perfect amount of clearance over that gusset luckily.
Gusseted the driver's beam mount
Drilled out the spindle steering arm taper and TIG welded some sleeves into the steering arms to be through-bolted
Beams and radius arms hung
Cut out the shock hoops and put a coilover in position. I'm guessing this will be about where the coilovers will be at droop. I need to mount a tire and bump out both sides equally and then compress the shocks to actually know where full bump will be, and built shock hoops and steering from there.
Decided to switch to King everything so I got some new 2.5x12" coilovers from Downsouth Motorsports for a great price. I think I'm just going to go for the secondary shock up front now too. I'll keep the 12" Swayaways in the back for now but my plan is to do a cantilever setup in the future. I feel like there is so much more that I've done but that's the gist of it.
