245 wandering steering

[DavidRhodes]

Bought this mint condition car three years ago and have gradually ironed out various glitches, mainly caused by lack of use. However, one fault plagues me. The steering started to get stiff and so my local garage fitted a secondhand steering rack. This was a marginal improvement, so we tried a secondhand power steering pump. The car runs very smoothly, but can suddenly veer off line. New steering parts were not available and it's of course possible that the replacements had the same faults as the parts removed. Any suggestions and source of new spares or steering parts would be very welcome.
