Any ideas?
Please notice the way the alternator bracket bolts up is different between the two.

Thanks!!!

What are the throat sizes of each?
Just by looking looks like a truck on the right and a car on the left. That's a guess.
Quick google shows the one with alternator mount for a 57 chevy.:chevy:

I believe the fresh one on the left is off of a 66-67 Nova. The last bolt hole near the firewall is a narrower depth which was unique to them, if I remember correctly.
