Differance in Parts, & Years?

[jknapp3]

Ok, here is my dilemma.. I have a 67 912. The front fenders are from God only knows what.
The driver side, no wheel well flair, (flat at lip) has a 7"est opening for the horn grill (My grills are 5"?) the "bucket" has the tabs for a later headlight?. Now the Pass fender, has no bucket tabs, and 7" grill openings, and a nice small "Flair" at the lip.
Now I got an other driver fender, It has a 5" opening, and a flair, and mounting tabs?
Tabs, no tabs?
Flair, no flair
and 7" vs 5" openings.
What do I have here?
I'm lost
Also, what years have opening vent windows on the doors?
Speedo in KM's, and has an ambient temp gauge (that still works!) 5 gauge car... Don't know if that would help or not? It's like the Johnny Cash Car here LOL
Thanks...
