blackened

Can anyone tell me the backlash spec's 05GT's 8.8" rear end w/ 3:55's? Can ya do one better and e-mail me a PDF of that section?

I assume that the lash should be set the same as before even with a shorter gear like a 4:10. My FRPP 4:10's are whining and the shop AND I are reluctant to put it back up on the lift for an entire day. I trust these guys but wanted to know what the factory specs are to compare to their setting.

Thanks in advance.
