I'd hate to build the car up, to then have to change them.

Change them it's not the easiest job to do when the subframe is back on the car

Of course they will look fine, that's because they aren't compresses and have the full weight of the car and engine on them. The rubber cones have a usable life of around of around 10 years max. So if they are 36 year old originals, or even if they have been replaced unless fairly recently, they could still be nearing 15 to 20 years old. Also don't go for the cheaper non-genuine ones to save money, you will be buying genuine ones in a few months time after the cheap ones have collapsed and failed.

Its not just if they are too squished though, as the rubber hardens with age.

Exactly! And springing that is too hard is as bad for handling and roadholding that those that are too soft, as well as doing the occupants and the subframe, shell and suspension components no good at all.
The other things that should ALWAYS be changed when the suspension is apart are the knuckle joints, which are cheap, and result in rather expensive damage if they are allowed to wear out.

I think the pre-76 mini donuts may have been made originally with a stiffer rubber. Also early donuts are not as tall as the later ones, this changed some time in the 80's?
If you want a really firm ride try putting pre-76 donuts together with the original Hi-Los!

If you want a really firm ride, try 20 plus year old knackered donuts and hi-lows wound right down so the front top arms are on the bump stops.
