37 or 38-39 fender skirts

[38 coupe]

I just got a set of 37 or 38-39 fender skirts with no hardware on them. They were advertised as 37 skirts. I have read on this site that the 37 skirts are longer than the 38-39 skirts. Can someone give me measurements on 37 skirts and on 38-39 skirts? I'd like to know what I have. I plan on using them to replace the after market skirts on my 38 coupe.

Thanks!
