I am looking to find some templates for WW2 style tank chassis that I can then put either GW turrets onto or just build those myself as well, also emplacements and flyers. These are for my guard army as I really dislike the GW WW1 styling on their tanks for Imperial Guard. Anything you guys can help me out with would be great as I don't enjoy the thought of paying almost 70 bucks a Russ in Canada.

Haven't seen or heard of any.

Have you thought about just mocking one up on graph paper, then transferring it to plasticard?
You could get some decent images online to use for measurements, I'm sure (though, you may need to enlarge the design, if the images are small).
