Nope, I actually need a shot of the back of the engine block, so I can see all the thread bosses that are there, and compare them to another engine I have on paper pics.

I'm thinking you may be able to use/modify an OEM intermediate shaft, which will allow you to run the shorter axle on both sides, and add in the extra 1" or whatever you need to the intermediate shaft, so you can center the engine properly without worrying about over-extending or compressing axles.

Basically, a shot of the back (exhaust side) of the block, with the differential housing as the extreme side of the image.
