Hi David,
It was worth checking as that was part of the problem with my '76 - took a year or so before the true cause of the wobbles was found!

You want to completely revamp the rear suspension? Talk to Peter Mulberry: http://www.mulfab.co.uk/
He has developed a complete replacement rear end for his own car (and a front end too). Whether he is selling them as kits is another matter...

Cheers,
