Thank you everyone. I now have a much better idea of what I'm looking at/for. The car is new to me and I have not had a proper opportunity to closely look it over and check things. I will first do the GoMog jacking up check (thank you John V6) and take it from there. I do understand that low speed steering is normally heavy but I have to say it is VERY heavy on this car - so maybe a clue to something seized. The SSL conversion is very appealing but cost may come into the equation. Once again, thank you for all suggestions - I will investigate when the weather in these parts improves a bit and report back on any findings.
