There's no issues that I know of in fitting panhard rods to any 2 seater Morgan
However there are 2 discreet chassis widths, 2 different axle brands, 4/5/6 and 7 leaf spring variations, with different locating pin locations dependent on year, nearly 40 variations of fuel tank of differing depths, fixing and fuel pipe locations, so you need to buy the right kit to suit...
