Looking for a little help---

I'm building a Worlds Car and having some trouble with the shocks. It's been a about 15 years since I've built a car so bear with me.

First off, how the heck do I get the shock cap bleeder screws in? I can't seem to get them threaded.

Secondly, the springs seem to rub against the treaded part of the shock body. Is that normal? The rear springs also seem to be too long and feel a bit stiff.

I've tried to build the the shocks 2x tonight and gave up frustrated. Help a brother out with some wisdom, please!
