If you want it to look right you will need HE ID panels for the bustle and turret side railings. HL's are way oversize and are all the same size. On the real tank the rear bustle panel is smaller then the ones on the side railings.
You will have to reposition the grenade launchers as they point to much to the front and are not aimed up enough.
The turret machine guns are very basic. The 50 cal can be fixed pretty easy the other will take some work to make it movable.
The front rubber mud flaps need to be painted black.
The road wheel center caps should be repainted to represent a shiny clear plastic with grease inside. That is what the real ones have as a easy way for the crew to check to see if the axels need to be greased.

Luckily I bought a HE within days of receiving the HL abrams are any other parts better on the HE than the HL?

Well, we don't use rear mud flaps and our VI-17 Panels are all the same size all around

The ID panels are really all the same size but the HL ones just appear to me a bit large. Even when using the HL ones I cut the side ones a little smaller in width and made the rear one square so it will fit the bustle rack without hitting the APU. If the stock tabs on the rear are used to mount it must be mounted pretty far to the right. Plus it leaves more room on the bustle to mount stowage like some 20 mm ammo cans.
Other then having items that can be used for stowage pieces on the HL if modified a bit, the HE is a very poor representation of a an Abrams as far as detail goes.
Even the commanders copula and 50 cal is wrong as they continued to use the very old 21st century M1A1 castings for the whole upper hull.
