K40 whip keeps snapping.

This is the second whip in two months. They replaced it for free but it's time to move on. Every windy day or time I go off road I lose it from it moving back and forth and snapping off at the base. Is there an antenna I can screw into the base that is fiberglass?

Or else I'll go with a perch, it's a flat top Volvo 670 so if you guys have some nice areas to route the wire feel free to post pics.
I could mount a set up on the back too but I don't know where to run the wire from the front. I'm not trying to tear the whole truck apart. Just get something decent it's just for a cheap cobra classic.

Thanks!

 

Edit, it's actually a k30.

Really my only option is a magnet mount because I don't really want to rip apart the dash on a truck that isn't mine to route it through the door for a bird perch. And don't want the wires all over looking like crap. I got the wires out of the way now since I used the top cb holder so it just runs along the ceiling and out the door and doesn't look bad.

Is there any good magnet mounts that can stand up to rough roads? I don't want another thin metal whip that will just break after a while of shaking back and forth. How's the hustler magnet mount? Or the midland one? The hustler looks stronger for sure.

I feel like thin metal swaying back and forth constantly will all end up broken. The hustler and midland both have springs and I can hook those up without drilling holes or taking apart the whole truck. Anyone have them?

 

Why would I do that? My truck is steel... I'm not sure I understand what you're saying.

 

It's a low roof, so it's just steel on top.

 

Yeah, it's already got a magnet mount on it. It just keeps breaking whips so I need one with a whip that's sturdier. I can be longer since the tractor is so low it won't hit anything.

 

Maybe. The k30 is super flimsy and thin so after so much movement it just snaps off right at the base.
