BB Front End questions.

[alsriv2]

Been on here a long time and finally have gotten myself into a mess due to lost parts from the PO of my '69. The truck appears to be a original BB and the block is a '69 with '71 heads. All the holes appear to be drilled and tapped for some sort of bracket combination.
Bought the truck roughly 5 years ago with the engine and all the accessories removed, disassembled and in milk crates.
Got the engine professionally overhauled, dyno'd and installed minus any front end accessories. Now I am finalizing the installation with all the front end parts, I am in quandary and am looking for help.

Most of the brackets on the front end are aftermarket solid steel. No "factory original" parts seem to be present. The Sanden compressor from the vintage air system installed had brackets for the pump to be installed on the passenger side. The power steering pump was a newer Saginaw with reservoir type unit installed low on the drivers side, and the alternator on the driver's side above the power steering pump.
I have the brackets for the Saginaw power steering pump and only one piece of the alternator mount.

On all the aftermarket sights I am aware of, I can only find new brackets in my engine's configuration when the water pump is short shaft.
However, the original water pump was a long shaft, and that is what is installed.
I have bought numerous things to try to make something work including an original BB power steering pump (separate reservoir on the fender) and bracket set.

This puzzle has aggravated me to no end so where to start? Change to a short water pump? What is the correct water pump? Where to find brackets for a '69 BB with the alternator on the driver's side with a long pump?

Any help would be greatly appreciated.
