Tring to find out if the front and rear sidelights(clearance) are the same from 1973 to 1978 or did they change in 1974? The basket case I got has no lites and someone welded up and Bondoed over the holes and if I want to get collecter insurance I have to put the lites back in.

Seems there were several types of sidelights depending on year and chasiss number. These pages from the parts catalogue may help you.

Thanks for the information. This should help alot.
