Have not fitted these. However I do have the rear bench from Minisport - It plugged in straight as these are the made in China ones (Choke) as per the front set and the Chinese copied a late production Moke. I'm not a fan of the quality of the vinyl used - gets very "soft" in the sun/heat and not sure how it weathers over time. Will get it retrimmed when I do my front seats.
I seems many have installed the front Choke seats during restorations so can let you know what they think of them
