We'll weigh the old ones and report back ... checking for bending will still be a useful initial indicator for the potentially affected cars as getting the wishbones off for a weight check while straightforward in principle is not trivial.
Would be even better if Morgan would identify and communicate the VIN range for the relevant early cars as it was a full switchover in production. I wonder if the MTWC might apply some pressure on this... Better than getting the DVSA involved!
