7 1/4 rear diff question.

Bump and thank you im not sure yet they are $150. Which is cheaper and easier to get than a 8 1/4 or 8 3/4 around here if anyone around here is selling one its usually just the case or its been shortened which i cant use with out tubbing. And also i would have to change my driveshaft length. I may get them just so i have some form of reliability untill i fine a good rear end. Until them more thoughts and opinions are appreciated.
