Quoting hbatts:- "Well Gents, Morgan has finally offered to replace my chassis free of charge----provided I pay the freight back and return from California to Malvern, sigh, such a deal. I've posted about my 2012 with a big crack on the front down tube. Freight should only cost me $3 or $4 thousand dollars each way, or only $8,000 to correct an engineering design fault especially after I fit Morgan's "upgrade" frame triangle to their suggestion. The reason for the frame "upgrade" was to prevent our frames from breaking. Prior to my fitting the "upgrade" I had NO frame cracks! Sadly much of the shine of my fun little car is gone."
Morgan are well out of order. If the thing had been designed correctly and the correct materials used in the first place, this cracking problem would not even be an issue. The fault is totally theirs and it is only because many of us do not want to see them take a big hit that it has not been taken to higher authorities as per the suggestion of OZ4/4. I think , as GTG suggested, MMC should ship a new chassis over to your dealer and pay to have them fit it for you.
