Reproduction door panels have a "puffy' appearance, like yours. Originals are much flatter.
U17 was available on any model. However, you have the body broadcast copy, which shows what was installed at the factory. I can't read your small picture very well, and by no means an expert, but I believe on line 3 it should have a cluster box and yours looks like "NF". That would correspond to a sticker on the back of the cluster. I don't have a list of cluster codes, but CRG should know. I am guessing Kurt knows these codes and NF is probably the standard speedo and fuel gauge.
Also, reproduction tachs look different. Post a pic of the tach if you want to know OEM or reproduction.
