Need A Measurement Cj5 Cj6 W/134 L Or F

I trying to get an idea if a design for a Header will fit my 56 CJ-5 frame and 134L engine. But my engine is on a stand and my chassis just isn't ready to have it installed.

I need to know the distance (taken parallel to the floor) Between the Oil pump and the inner edge of the frame.

I'm running Saginaw steering and an electric fuel pump with a DIY Dual Master Cylinder setup. SO I have only the 3/4" D steering shaft in that area and it can be moved up and down a little depending on where I run my U-Joints. SO I am hoping there is enough room to fit the Two Y connectors (1.75" wide) in that space.

I'm working on a Tri-Y style header for my 134L
