[SCOTI]

Ultimately, the plan is the upper C/O bracket is a bolt-on & sandwiches the original upper a-arm mounting bracket (also using it's retaining hardware).

Since material will need to be removed from the upper air spring mount (so the C/O can clear), there will be a plate that can be bolted under the remainder of the mount & will locate a bag where it needs to be (much like bolting the upper bag plate under an OE crossmember) if I ever want to switch back.

The lower C/O mount will also bolt-on to a 'bag' style a-arm. It's just offset as required.

The shocks (coil-overs) are longer than what is typically spec'd for these C10's. I follow the principle often stated by Rob @ No-Limit…. Run the longest shock that you can for the best travel. Conversion kits are limited by the stock suspension geometry & real estate under the hood. Since I have aftermarket stuff & I'm even tweaking that, I'm adding stroke length for the shock in the design. I'll be using a 5" stoke shock which should allow 3" compression/2" extension while not being too invasive. I used that philosophy & similar dimensions on my dually & it worked well.

Final ride height mock-up is very similar to Gringoloco's swb w/the PB C/O front set-up. I feel my set-up has the upper C/O mounting point about 1-2" higher than PB's does thus a slightly longer shock can be used.
