prevent seizing checking clutch cable run on '83 BRAT

[Geluso]

Hey I've had trouble with my clutch cable seizing up on me. I'm replacing the cable now and I want to make sure I have everything right. Anyone care to look over where I'm placing this clutch cable and offer advice to prevent it from seizing up in the future?

Specifically, I'm not sure what way is best to route it once it comes through the firewall in to the engine bay.

Also specifically, the angle looks so extreme inside the cab when it goes through the firewall and into the pedal mount.

Someone please tell me what I'm doing wrong! Thank you.
