I would watch for another issue, 2011 was a year of the worst leaf springs at MMC. My new P4SS completely sagged in the rear on the driver side after only three quarters of a year. I got new leaf springs under warranty that held up well until I sold it. Ask if yours are still original, if they perform you don't have to change but most likely you have to.
Based on my experience of Monty (who Morgan built in 2011), I have to say this is fantastic advice from Heinz
My original springs were absolutely terrible
What Morgan originally fitted to the rear of Monty, were springs by name only!
