Birdcage question.

[racerj5]

I stripped my GRT after crashing it and I have a Rocket that I want to put the parts off the GRT on it. Are there universal birdcages, or are they specific to the chassis. If so, what's the difference? Thanks

There are different distances from brake caliper to 4 link. And either of those points to shock mount.
