The Rubicon tool stowage is mirror image of the tanks in the photos .
Doh!
You mean on the rear plate not the side, ignore the above.
I have just run through the photographs of the M4 hybrids on the Minutia site and all the examples have crank handle to the left, tensioner on the right.
On the (other) PSC M4 page on the site, the crank handle is still to the left, but the post for the tensioner is left of centre, handle to the right.
The Alco page shows tensioner to the right, but the hybrid POWAB shows the crank handle on the right, not left but no tensioner.
Baldwin's show left of centre tensioners.
As an aside, the nubbins between the hinges on the rear engine doors is the mounting point for the exhaust deflector grill. You can see them just below the filters on my model.
