OK - Keith I think I understand the Canceling out Point - in 1 Plane
as We look at it ( Side View ) - how about ( Top View ) or as I always say
The Other Plane `\ : - )

That's the Trans Offset & Pinion Off Set - I'm concerned with ?

So Both the Out Put Shaft on Trans Tail and Input on Pinion - would
need to be Same Dim. Off - ( Center Line of Chassis )
Hence - Top View ..

Also - May I add seeing many Trucks have Center Shaft Bearing - Total Length of Drive Shaft would be ( Considered )
Both Half's and ADD .500 to the Dia. - due to extra Support OR
Just Consider the Longest Drive - Shaft - Minus .500 Dia. Due to the Presence of a Bearing Support ?


Above ? is for everyone having Any Experience with these Considerations - as many have Changed Rear Axles & Center sections ..
