A little late but re your original question “Without trouble” When I first fitted 185’s all looked fine stationary but very occasionally one rear side would just touch the inner wheel arch (at the 2 o’clock position) whilst cornering resulting in a slight polish mark to the grimy black underseal just inside the arch. An unlucky characteristic of an asymmetric hand built car that is prone to flexing. It was easily resolved by fitting a Mulfab axle centralising kit. Now there is loads of clearance all round and it also looks so much nicer with the wheels in the middle of the arches (where perhaps Morgan should have positioned them!).
