Big John,
thanks for that , but it makes no logical or financial sense to have so many different parts? I can understand different part numbers to some degree, but still parts must be interchangeable.
ie: early 1970s Bentleys had many Citroen parts for their suspension, early Range Rovers had parts from other cars, Jenson used other car parts, it’s common practice. If you take an x type apart you’ll find ford labels, Some Nissans have Renault parts , many cars are fitted with Mercedes engines, they will all have different part numbers, but will still be interchangeable!
so surely someone must know what is interchangeable on the s type??
