If you can live with 14" wheels, I'm pretty sure Morris Minor has the
same 4" bolt circle. Sunbeams, at least the Alpine, had 4.25" circle
(like most English Fords, and I think Alfas). Old Lotus Sevens were
3.75" (like Triumph Spitfires and Heralds); maybe the very earliest
were different. Smaller BMC cars (Sprite, Midget, Austin) were 4"; the
larger sports cars were 4.5" (MGA/B, TR3-6, and most early Japanese).
