Here's some examples...a couple M-46 and M-45, but same deal. Empty cans you can put anywhere, but not much sense in carrying empites. A couple in the turret side stowage rack would be a good touch. They would normally be water. Oil cans are generally carried tied down near the engine to keep warm for easier pouring in very cold weather. Fasten them down with rope or strap. There are lifting
eyes (triangular) on the engine deck near the fenders and footman loops can be installed anywhere for heavy straps, so there is a good place to carry 1 or 2 jerry cans. The lifting eyes are moulded on, but you can drill a hole or simpy CA glue the rope so that it appears to go under....or scratch make an eye that stands up. Tanks always carried rope to tie down personal gear etc.

Commander mentioned track guard (fender) braces. These were added post WW II and easy to fabricate using soldering wire. Just flatten out the parts for the turnbuckle with flat nose pliers. Some guys have made some really grat ones with threaded rod etc, but
the soldering wire trick does good on an RC tank that's going to be bouncing around and not on museum display..

Early Pershing skirts were bolted on, but later and with M-45 & M-46, there were mounted on slide hinges that could be lifted up by removing two bolts. Either way, they were a PITA and got in the way of maintenance as well as getting torn up and getting tangled in the tracks , so most were simply taken off or as the Marines showed us, folded up to provide MG ammo stowage. In Korea, tanks needed as much MG ammo as was possible to carry.
