Final drive interchangeable

[Fab333]

do all years vmax from 1985-2007 use the same final drive and shaft?

Yep/yes

But some markets had a different final drive ratio. i.e. 2.851:1 (full power versions) or 2.567:1 (non full power?)

Is their any way to tell what the ratio is? or do i have to open the final drive up and check the crown wheel?
do the final drives have different part numbers on the outside of the housing?

The actual rear gear ratios (not including the middle gears on the trans which are in your numbers) were 3.66 (US Spec) and 3.33 (Venture and other non full power).
