Rubber suspension

[sagalout]

Once I get the welding out of the way (about in a decade), I'll be turning to the suspension. Apart from the obvious, how do I tell if the rubber cones are knackered. What's available? Some places advertise ST Rally types others say only "standard" now available, etc etc. What do I need (can I get) for the 73 Clubbie, road & road/rally car. I will be changing the knuckles if knackered, I should be able to see that.
PS will be changing the sub frame mounts for poly type unless you think different. Against solid 'cos of noise transmission and think I need a little "compliance" for road use.
thanks folks
