Hi Bruce
if you set the model on a diorama, you can hide that spot with something (foliage, rocks, kneeling figure, log, mud, etc). You could maybe even fashion a part from plastic card to replace the missing track, given its such a small piece, it would not have to be perfect, and would be hard to spot if you did even a fair job on it.
but I may be able to help you - I believe I might have a small piece of Fujimi PZ I vinyl track, somewhere, though I've noticed that Fujimi track, when exposed to the air can 'shrink' over the years so it may be a bit underscale (but you could line it up on the outside edge so that wouldnt matter much). I'll post back within 24 hours to let you know if I've found it. (I have a small mountain of spares parts boxes in my roof, so may take a while to find)
there is a handy T34 article comparing various T34 kits in "On The Way" also, I found it useful for a Military Wheels T34 Flakvierling that I'm building. It only deals with the 1/72 kits, but may be useful to you anyway. Maybe you could get an Airfix T34 as well and do a 3 way comparison as I think its 1/76 also, and they only cost about $6 AU these days. I've got a couple unbuilt in my roof, and the detail on the hull is very simplified, by more modern standards.
