Can anyone tell me if it is correct I was replaced later?
Thank you
Off topic but this is an interesting topic! Generally it's accepted that 75090 = plexi and 75190 = sapphire. However, others on the forum have posted their 75090's with sapphire. It's possible that there was a transition period between the 2 references.
