How are these tracks put together?

You can view the instructions here:

Indy-link, two parts per link: link molded with end-connectors + the upper part of the guide horn.
Assembled in a jig and then glued solid.

One issue is that the end conenctors are molded together with the links which is perfectly OK for straight sections but it doesn't look good when the track wraps around the sprocket and the idler.
Correcting this requires slicing off the end connectors and the lower part of the guide horn or central connector. Then you need to reassemble the link again.

I have done this for a couple of kits and the easiest way for me was to rebuild those links on the idlers and drive sprockets, using the wheels as guides to get it all straight.

If two track links are angled 20 degrees then the end connectors between them will be angled 10 degrees to the each track link. It divides the angle in two equal parts.

These are individual tracks with a track jig to help with the build.

I usually bend those links applying torque to the end and central connectors. Once you've found the way to grab the pieces between your fingernails, it is easy and quick. It has to be done before gluing the guide horn.

It works for some kits and less well for other kits

It depends on how soft or brittle the styrene is.
Test on some other piece of styrene from the kit first.

I've built both T-64 and T-80B of Trumpeter in this way, I would be surprised to see unexpected problems with the Oplot.
