Could the lens be a replacement from back in the day? Glo-Brite and Dietz both made a lens in the 60's 70's that were collision replacements.They were a good quality lens until the reproductions came out.There biggest flaw was they were not 100% visually correct.It may have been a RS replacement.....
As for the space saver,I have never heard of a rally wheel used.It would have to be a special code 14" rim to be correct.I believe the offset is different as well....I have the option in my 68.....Hurry up spring!
