Ian, I think your car is from the era when MMC bought some offshore low grade leaf springs & the issues you describe, other owners have had
This firm used to be (may now be back) the original OE manufacturer, using pukka quality steel & hand forged in the heartland of proper heavy engineering
Owen Springs, Rotherham, tel 01709 710700
Owen (I think) now supply MMC and probably aftermarket suppliers like Mulfab, but Caveat Emptor
Cooperman. Sent Owen springs an enquiry. Their web site does not appear to cover Morgan under their leaf spring menu.
regards
Ian
