Why is this and how do I tell the difference of the hulls?
Reason I am asking, I just bought a plastic lower hull from Ebay for $20. The seller says it was for a Jagdpanther, however I just got a new black steel gearbox from Mato, it is short shaft. I already have plastic gear, long shaft parts I can just swap into the gearbox if need be and that's what I'll do if it needs that length (to buy the shafts separately, even the plastic gear ones, costs as much I might as well just buy another gearbox for $10 more...the shafts are dirt cheap it's the shipping...to just buy the two metal long shafts comes out to $26 shipped and that's the cheapest

I have metal sprockets and plastic tracks on the way, even the upper Jagdpanther hull from RCparty ($40 it cost) yet these are the same for both model Panthers. Aren't they?
