Sway Bar Size

[rainman]

I know that all 70 LT-1s should have come with the standard 3/4 inch sway bar. However, the bar on my car that appears to be original is 15/16th. Any possibility or rumors that 70 LT-1s might have gotten larger bars? The springs are standard with HS decal still in place. My car is a Feb build.

Thanks
