Damaged bayonet on Tamron 70-300mm VC for Canon

So my old boss gave me this lens for free since one of the three metal tabs on the bottom side had a ding in it that made it impossible to mount to a camera. For the time being i filed out the ding in the bayonet so it'd mount fine but now Id like to actually fix it permanently.

My question is if I buy a "for parts" Tamron lens that has some other issue can I use the locking bayonet mount of it? Or are they specific depths to specific lenses. From my observation they appear to be the same part.
