Would anyone have an idea what type of Cooper these Armstrong externally adjustable, coil over ,spring shocks might have come from? They are serial numbered AT9/SA 2945 - dated 8/67 and have an extended length of 12 1/2 inches, and AT9/SA2674, date 10/67- extended length 15 1/2 inches. The dates on the shocks don't seem to match the style of a set of front uprights and 4 stud wheels -15 inch dia, cast - currently on an old car in the garage. Girling discs- 11 inch- 2 spot cast aluminium calipers- with the calipers at the back of the wheel , not the front. This is bcoming one of life's puzzles. Thanks, Howard.
