Ram Horns and Alt Bracket

[68_Step]

On my 67 C10 I now have new ram horn exhaust manifolds that do not have the alternator mount built into the front edge of the left side. My old one that did have the mount broke and leaked badly at the crack.

My old bracket bolted to the water pump and the left exhaust manifold - he bottom of the alternator bolted to that. There was also a adjustment arm that went from the intake manifold to the top of the alternator.

How do I set up my alternator now? I see some folks have a bracket that bolts to the front of the left head using the 2 holes there. Is that a factory part? Or after market?

I have a short water pump and a 1975 (I think) 350 that was installed by the PO. My crank pulley is a 3 groove using the single add on pulley.

Any suggestions, alternative mounting thoughts, or part numbers would be appreciated.
