Does any know what length stem...

Came fitted to medium sized GT I Drives in 2001?

I would have thought it varied depending on the model of I drive. I had a 2001 Avalanche and a 2003 I drive in the large size and both had 110 stems.
But surely it’s best to fit the right length stem for your individual dimensions and preferred setup? I ended up changing both the above stems as they were not right for me.

I would say any Stock Stem has a 10% chance of being right for you.
