I did this 10yrs ago with my gold coupe.As said at the time,you cant fix to the body for the top eye-it wont be strong enough. My solution was to buy mini[?] dampers from Dampertech and fabricate a tower which bolted to the metro subframe [with the sphere mount removed] and had a mount for the top eye of the damper.From memory I think the dampers were 10 inch. Of course there was not enough room between the upper arm and the body,so the solution was to cut a square hole in the top of the arch and seal it up with a square 'top hat' made of alloy sheet. The damper could then be fitted by pushing the tower- with damper attached via top eye- up into the hole and bolt the tower to the subframe.Then fit bottom eye to the top arm with a shackle plate.
It was fairly successful,the main problem being spring rating.I tried 3 different springs before I was reasonably happy with the ride.From memory[a bit hazy] 180 then 240 and finally about 280 pounds.
I should have taken my mate Ians advice. Look at the plate in the engine bay which gives axle weight for front and back axle. Take front weight,add 2 passengers and divide by 2.This should give you a good starting point.
I should add that the dampers were adjustable for ride height via a ring collar. Looking around the shows,there are better quality dampers which may be better at surviving British winters,the dampertechs corroded quite a bit.
Good luck with your conversion,Stan.
