Need pics of square coolant overflow bottle + bracket

[72 longhorn BB]

Hey there, Has anyone got pics of these items off a 1973 or later p/u?

My 72 has what i think are these, which were obviously afterfitted, but it works great.

Only thing is the bottle is cracked and I want to confirm it is the proper one before reordering.
Also, I could use a square bottle bracket, as mine is almost rusted out.

Anyone got a spare they want to consider parting with?

Thanks in advance
