I was hoping someone with access to a Mitsu Evo shopmanual could post a schematic of the front chassis crossmember. I am trying to get a picture/drawing of everything that bolts to this sub-frame (front lower suspension arms, steering rack, transmission mount, etc...) and the torque specs.

Also, do the folks running the more fully prepped road race cars use this factory sub-frame piece as is or something else? The closer I looked at it, the more I realized it is a fairly complex piece in terms of shape, varying gage/thickness of the steel, and how it is all welded together.

Thanks in advance.
