I measured the idler and Pittman distances and final tie rod positions and its an exact match for the stock installation.
I mounted the rack set up and with my center sump pan it bolts right in! It looks as though the only stumbling block is a extra steering support under the hood.
With it all lining up the same as the stock box and steering linkage components, im not seeing any problem with bump-steer.
Ill see about mounting something off the frame for support this weekend.
If anyone has a suggestion for the support im open to suggestions, using the stock steering shaft.
