4500 mockup begins-eng location ?

[SunSoaked]

I got an old smallblock bolted up to the 4500 and dropped it into the frame rails today for the mockup stage. I moved the front x-member fwd 3 1/4 inches, cuz thats where one set of holes lined up. Figured it should be close to what I need. Gains me a little clearance between the HEI cap and firewall and moves the trans shifter fwd to a more usable position.

The shifter now will come thru the floor 2 inches behind the front cab mounts ( see the black x in last photo ).

Anyone gone thru this before (Steve-Larry)? I would appreciate any feedback to save me any grief if I'm overlooking something. This is my first shot at this.
