looking at getting 4.10's have some ?'s
 

i have a 98 t/a ws6 six speed. i want some 4.10's now i am looking at getting these from speed inc. do i really need a rear end girdle??? there is a kit that has a rear end girdle, the 4.10's, masterinstall kit, and a speedo recalibration. what all do i need. its 529 for that kit. plus i will have to pay for someone to install it for me. so that is going to be way too expensive. can anyone tell me what to do, or have any suggestions??? any will help thanks alot.
