Two General Questions about my 1974 Dart

Frankenduster said
Dart fenders are tricky.
Here is a breakdown on them.

67-69: SAME stamping. 67 has NO side marker lights or holes to mount them. 68 has round side marker lights. 69 has rectangular REFLECTORS.
70-72: SAME stamping. 70-71 has rectangular flush mounted side marker lamps. 72 used a new corporate side marker light shared with several other models.
73-76: Exterior stamping is identical to a 67-69 model, yet there are several differences. Corporate side marker lamp in all years. Headlamp bucket is moved slightly from the position held in the 67-69 fenders making a direct fit difficult. You can cut and move the headlamp mount within the fender though. 1976 models had a slightly different mount on the right fender for the antenna.
NO Plymouth fender interchanges.

You are 100% correct, i couldn't have said it better myself.
The ''corporate'' side marker he refers to is the plastic ones that attach to the fender and sticks out a bit like on your car as it is now.
All chrysler products used them from '73 and up so they are easy to find, you can probably buy them at your Chrysler dealer new. I don't think they are very expensive either.
On another note, unless you really know what you are doing when installing a new windsheild, it's better to take it to a glass shop and let them do it. Find a glass shop that really knows how to install one in an older car or it will probably leak. Buy the windsheild from them and get them to install it is your best bet.
Good luck.
