First time I've heard of the instrument hole , Should be able to transpose the 40.300" measurement to the out side firewall.
There should be some small shims between the front mounts and cab I didn't measure mine but was about 3/32" to 1/8" per side, but I know it wasn't more than 1/8".

No shims from factory in between frame and back cab mounts.
