Air adjustable shocks, damper mounted coils or air bags all have mounting problems if available in sizes to fit a Morgan
I'd like to see the MogVette set up though.
I measured my 4/4 today, it has 5 leaf springs, 70 mm clearance between diff and ply cover, approx 35mm between diff and hoop.
Springs appear slightly past flat.
Noticed one shock has given up since we had a run to Melbourne and back 2 weeks ago, 1900kms in 4 days.
I think it may be re spring time.
