The London Roadster has a rear shock that is mounted in the center of the rear coil spring. The front has a coil over shock. If you remove the rear shock you should be able to buy a matching shock. Must do both sides in the rear. If you can’t get a replacement then get a shock that would be in the middle of it’s throw when the car is sitting on the coil’s only. That way you shouldn’t ever bottom the shock out. The front and rear shocks have different mounting ends unless they have already been modified. Hope this helps a little.
