Could anyone tell me how to tell if some plug wires are repops or original?
I have a set from when I bought the R/T but they look pretty nice.

Post a few good close ups of the script on them as well as the distributor boots

Date codes will be a give away also.

Reproductions have date codes as well, the differences between OEM's and reproductions are quite subtle but they exist.

Im guessing repops because of the condition but here are two. I can get more.
Thanks!

What I meant to say is that all the reproductions have the same date codes (ex 70 wires are 3rd qt of 69 if I remember right)and it normal to see on a set of original with 2 or more different date codes.Usually not a matched set.

Is the distributor to coil wire boot 100% black or does it have a slight dark red hue to it?

all black boot and the wires are all dated H 3-67.

Yep, sounds like repros.

Here's an original coil wire boot

These are NOS wires (including the coil wire). Notice how the coil wire has white script? This was common.
