If i had the chance to fix up the Leman Russ tanks I have again ,I would go with having the body back to front the front gun port is ideal as the bolier and what is now the rear end has the potential as a new front.
But as it is i'm going to either totaly cover the tracks at the top or bite the bullet and try to remove those track pieces and "lower" the tracks so its less WWI to "Holt" tractor -still have the tracks covering the top 1/2 but have them as mudguards/gantry on which to place extra storage.
