273 auto trying to find the 'tick'

finally some pics...

This is the bracket he bought. It didn't fit but it gives you the idea of what i will make once i identify the flywheel he has. The second pic is the template he made to use to make the bracket. Dunno what the first bracket fits but shares 3/5 holes. The third pic shows the other holes lining up. The last pic is of dudes template on what i believe to be a small block bell.
