Welcome to the forum,
This forum is full of great looking trucks; packed with great mod ideas and there are loads of knowledgeable and experienced people here.
You could try places like Rockauto, Napa, Autozone, etc for prices on replacement lines, or buy the tubing and make your own. If you've never made your own before, it's not easy to get it looking good.
AND - We all like pix! Got any to share?
Enjoy the Z!
