LS1 guys, need a quick measurement!

[Superman09]

Looking for someone to help get me a quick measurement. I need to know the thickness of the alternator bracket where the bolt goes through. Bottom most portion of the bracket, from front of bracket to the back where it meets the block. I don't have one here and need to put a dowel in this place so I can replicate it for a mounting location. Thank you so much, I have attached a photo for reference, thanks!

The inserts move so that number isn't always the same

Just something close, the couple mm of the insert is not important for what I need, thanks!!

Edit: Thought I added the measurement in case the photo was blurry, guess I didn't. 3.778" on my spare bracket
