I have a 1971 blazer 4x4 and a 1975 K10. Eventually I will replace both. I learned that Cardone and others are using the same number for a 71 blazer and a 75 K10. They said luck of the draw for what you get. Is there an additional number at the end for example 3L or 4L on the case that would tell you the difference. Thanks
