UPDATE!!
☆ ------------------ ☆ ------------------ ☆
So I recently decided the factory firewall looks ugly with all of the useless holes for the climate control system, and old brake and clutch pedal assemblies. That will be removed soon, for now I removed the steering column support and other small miscellaneous brackets that are spot welded to the upper cowl area.
Here you can see one of the three relief cuts that I made in order to insert the new frame rail in an inch. I then reshaped the old rail to match the new rails profile and tacked it in place.
I then triple checked all of my measurements and the angles on the new frame rails to ensure they are exactly in the same position as the old OEM rails. After it was all in spec I went ahead and welded them permanently in place, you can see a Rosette weld in the second picture along with the temporary Jig/brace to hold the width of the rails.
Next up I plotted and precisely drilled the holes for the temporary OEM crossmember. I was even able to drop in the OEM paired bolts through with no binding or any fitment issues.
Now I put my 3D design skills to work. I came up with 3 designs, from complex to simple, for the strut top plates. Each one was tested at the max load they would take if the coil over was fully compressed (6" compression 10k springs = 3360 lbs of force). I over engineered these top plates to take over 10,000 lbs of force.
These top mount designs will incorporate a .75” offset to widen the front track and allow for more angle. I made an exact model of the PBM Pro camber/caster plate to make sure I won't have any interference with my design.
