Power Steering Problem

[Lippyp]

Greetings from the very damp north west of England! I need some help and advice.

My truck has had power steering fitted at some time in its life. Whoever fitted it obviously couldn't get hold of the proper pump mounting brackets and fabricated (badly!) their own. This is not unusual in the UK as the right parts can be difficult and expensive to source, we don't have scrapyards with loads of old Chevys sitting in them! The engine is a 1969 350ci with the pump located low down on the drivers side beneath the alternator. Pictures can be taken if necesary.
This is now causing me some problems as the belts are slightly out of alignment and are wearing. I also need a new pipe as the one on the pressure side is cracking up (the rubber) and I don't know what vehicle the power steering would have come off.

Questions:

Is the pump in the standard location for this engine/year

Are all the pipe fittings the same (flexible part of pipe is approx 18" in length) across different applications. Is it just length that is different?

Does anyone out there have a secondhand set of power steering pump brackets for sale? Are these universal or are there differences between years/applications?

Help!!!
