Oil pan dimensions

I'm looking for oil pan dimensions for aftermarket and factory 3rd gen hemi pans. The main dimensions I am interested is the depth from the pan rail at the front where my power steering rack will be and the total depth of the sump or lowest point. I only have about 1.75-2" room between the rack and block. Tincup used a Canton oil pan that so far as I know is discontinued and the Milodon didn't fit his, nor did the Charlies. I've been considering the truck or jeep pan but am concerned about their total depth for ground clearance. Additionally, does anybody offhand happen to know what that rod above the rack that crosses between the steering boots is for? I'm contemplating whether or not I could bend a new one to go down around the side before crossing to gain some more clearance, not sure as to it's function though.

I appreciate the help,
Ryan
