Let me pick your anyone's brain for a second. I have a bonebrake bushy but the z-4 bolt swelled up over time. Obviously they don't sell that bolt anymore but I've heard that the Techt ego bolt might fit. Does anyone know official it fits the bonebrake?

Believe me, I've tried, haha. I wish ego bolts fit, but sadly, they do not. The distance from the pin to the air transfer hole is the right length, but the diameter is too big, and the bolts are too long.

But, I had a halfblocked cocker (done by curt) and a half block auto cocker bolt was the same dimension as a bushmaster bolt. I'm not sure if that applies to every cocker bolt, but I would definitely try that route, Maybe pick up a cheap cocker bolt, and try it out (I'm 90% sure they are fully compatible).

I just sold all my spare bushmaster botls too.. Try asking on icdowers, mabye somebody else has one.

since your bolt wont' fit anyhow, maybe you can try to sand it down; you won't have a good seal though, unless you use orings or use a lathe

if you need a stock bolt, i have one that i can sell.
