I purchased a set of new front upper T1 a-arms in a private sale. Are there any identifying marks on the T1 arms - to distinguish them from the stock replacement Z06 a-arms ? In other words, how can I verify that these are in fact T1 a-arms ? Also, are the T1 arms identical to the standard issue Z06 replacement arms, other than the stiffer bushings ?

Do they have a part number stamped somewhere? Even the $2 plastic door plugs I just bought have a part number on the part.

they are the same arm, they just have a stiffer bushing. I doubt they have different labeling on them. Poly is much better regardless.

on both counts they are not going to make a separate casing to have a different number.

ok...but you would think there would have to be some means (marking / labeling / tag / etc) that would ID them as T1 pieces.

I've bought brand new arms from a forum sponsor and they had labels with the P/N and GMPP logo attached to them.

John Shiels

that makes sense as it is just a label which is cheap

FWIW, GM swaybars show up the same way... labelled, not stamped.

It was the same on the sway bars, a paper label attached with a thin metal wire through a hole in the part.
