Is anyone else having problems with the T-34/76 Track. I did mine as per instructions and they look short. Here is a photo of the model

Here is the scene I want to model.

I'm willing to believe it was my fault -- I wondered from the start what the heck the forward idler wheels are fixed with polycaps -- but where is the mistake??
BTW apprx 1 link is to be inserted to get the look of the picture, but as the tracks are of 2 different types you can only include 2 track links and then the track is much too long
I'm desperate, PLEASE HELP!
