Going from a J to an E will require a fair amount of rework. In addition to the stepped frontal armor, the sprockets, idler, antenna placement (and mounting), rear mufflers, hull side vision ports and turret doors also differed. Oh...J used steel return rollers and E used rubber tires and the track on the J is wider than the E. This conversion will keep you busy.

Wrong tracks for an E or a DAK tank. Those have the ice cleats, which were not used in North Africa, and are too wide for an E.

I'm building plans to convert an HL F2 to a DAK G. Here's some references that I used or found (haven't reviewed all of the books):
