turrets compared

[ohiohmmwv]

I have TM 9-2320-280-24P-1 HMMWV Parts vol 1.pdf (and vol2) which shows the exploded parts diagrams of the turret. I assume this is the older version. Are there any TM's for the late model turret?

Are any parts interchangeable between the 2 turret versions? Especially in the turret support, like the B pillar supports?
