Are there any dimensional drawings available to compare your steeringbox to the stock powersteering box?

Reason for asking is that besides myseld, a number of folks are looking into installing a modernday Hemi into their Mopar A-body, while retaining powersteering.
Currently, at the driversside, the Hemi's exhaust will interfere heavily with a stock powersteering box.
It would be nice to see if your box provides more space so it won't be necessary to install a rack&pinion system for instance.
