The only modification should be G which measure pillar to the master cylinder.
So how about we add G2 which will be pillar to pillar.

What I have found so far is:
* intake manifold surface of DOHC 4g64 head to the pillar is 12"
* DOHC 4g64 head width is 7.5" intake to exhaust manifold surface
* center line of DOHC 4g64 head to outside edge of 1G intake manifold is 14.5"
