1970 340 Factory pulleys and brackets.

This is a Dec 12 1969 build date LM23HOR
I found a 340 with the correct date range.
This is being set up the same as the factory did it.
There has got to be someone out there that knows what the correct pulleys are for this setup.
I know this is an odd setup, but it is a factory
Air conditioning and alternator only setup.
No power steering.
