It's later than that. It's got the big hole for the fan instead of a grille cut out on the inner wing.Lol, that part of bodyshell is from a 1988 onwards car- two heater hose holes on the bulkhead
I think that only came in with SPi and MPi.
MPi doesn't have a hole in the inner wing, since the rad is at the front. So it's older than '96 at least
Some MPI's do have a hole in the inner wing as well as a front rad, i bought one of the last MPI shells off the rover production line and it had hole in inner wing and front rad.
