I like your plan on this.
I have a cab that I can measure this.
Where is the location point on the firewall left /right?
In simple/better terms a measurement from passenger side a-pillar where the hinge mount
or just from
The straightest part of the cowl on the Passengers side?
What's the tolerance you are looking for?
Tape measure or 0.100
I am a Machinist I can't help it
I can get you a picture.
Just let me know.
