I am working on the above mentioned model, it is also a convertable. I do not have a set of micrometers handy with me and need to determine the size of the pistons. In the service manual it states there were 3 sizes used that year for that model, listed as follows:
5.0L (1)
Red Piston 3.9989-3.9995 (101.572-
101.587)
Blue Piston 4.0001-4.0007 (101.603-
101.618)
Yellow Piston 4.0013-4.0019 (101.633-
101.648)
5.0L HO (1)
Red Piston 3.9972-3.9980 (101.529-
101.549)
Blue Piston 3.9984-3.9992 (101.559-
101.580)
Yellow Piston 3.9996-4.0004 (101.590-
101.610)
5.8L (1)
Red Piston 3.9978-3.9984 (101.544-
101.560)
Blue Piston 3.9990-3.9996 (101.574-
101.590)
Yellow Piston 4.0002-4.0008 (101.605-
101.620)
however there are no identifying marks or colors whatsoever on the pistons. How are they identifiable? Thankyou
