06 masters birdcages? rear end?

[00racing]

I have a 06 masters smack and it has the GRT birdcages on it. The entire rear end may have even came out of a GRT!.. Im unsure.... I have a mastersbilt setup book but it has no information about the rear end other than location. Does anyone know what the rear end should measure and if the GRT birdcages are ok to use. Im kindof new to late models and want to make sure things are in there proper locations. Thanks

There are two typical lenght rears used with a GRT. First, I would pull the axles out of my rear and measure them and that gives you your rearend measurement. Then call Mastersbilt and talk with them and they can tell you if the rearend is the right rearend for your car. Also, measure from the rotor to where the spring hooks to your birdcages on each side and give that number to Mastersbilt also to see if the birdcages need to be moved.
