Nice score Chris! I have one of those, too. It's a '68 TL code HD 31 spline axle shaft model, which was supposedly used behind MT OAI cars in '67 and '68 only. Do you know if yours is a 31 spline unit? I remember someone saying a while back that all 3.42 and up ratios in '67-'68 were 31 spline units, but I have never heard that from any other source so I am not sure of its validity. I'm a bit behind you in my collection - I have a 2.56, a 3.23 posi, and the 3.42 HD 31 spline rear. I do have a set of Richmond 3.90s that will one day replace the 2.56s and make that one a useful rear, though. Kenneth 1971 Cutlass Supreme convertible Phoenix, AZ
