Hello, everyone. I am new to this Forum thing and this is my first post. I just acquired a 1970 hardtop that was originally built with a 3.55 Safe-T-Track rear end. Can anyone tell me what the correct rear end casting number should be for this unit? Thank you.

I would help if you give us yours along with the axle code to verify the 3.55's. :thumbsup:
