Hi DeeDee,
The perfect setup is for the bottom rebound spring to be just kissing the bottom of the stub axle at rest such that you can just turn the spring by hand. It's tricky to do because of all the slippery grease but if you us a small rag to hold the spring, it can help. It's not always obvious as you can get some binding at the bottom of the spring in the cross head so persevere with trying to move the spring if it does not seem to move easily.
If it still does not move, get someone to sit in the passenger seat and bounce a few times. If the rebound spring length is just a fraction too long the loading of the main spring will just give you a bit of extra clearance and the rebound spring should then be clear to rotate.
The Morgan front suspension has a lot of stiction in the system and I quite often find that when I get out of the car and check underneath, the driver side rebound spring has a few mm of clearance when I've been driving on my own as that is the side that's had more main spring compression and the stiction in the system has not allowed the main spring to settle at the normal ride height.
All I do then is bounce the front end a few times to even up the springs and usually find that the rebound springs are evenly balanced and just kissing the stub axles.
It is not unusual to get that slight mismatch in ride heights with the car in a static situation so bounce it a few times and re-check.
Of course none of what I've said should rule out a thorough check of the front end to make sure there is nothing else going on but a slight mismatch side to side in static condition is nothing to worry about.
BTW, the old set up was for the rebound spring to be in compression. If it is you will never be able to rotate the spring and in that case you could have a problem because to have one spring in compression and one with 5mm free play suggests something is not quite right.
Could just be excessive stiction that needs a good lube or a sagging main spring on that side. If the car is still under warranty and you are new to Morgan suspensions, It's probably not a bad I idea to discuss it with the dealer anyway.
