1973 PLYMOUTH VALIANT SCAMP, PRICE REDUCED BY $1,000

Jeff, I had a guy look at the car last week and said he thinks its a 904. Regarding the rear end I don't know what you are referring to. I'm not a mopar guy, I got this car on trade 6 years ago and know little about it. This website limits the number of photos to ten. Sorry this hasn't been very helpful. Paul
Please post a picture of the fender tag.
If you don't know already, it is located on the inner fender on the driver's side between the battery and the washer bottle and is rectangular in shape with numbers and letters on it.
While you are at it, take a picture of the rear differential from the back and the bottom of the transmission pan.
You can post more pictures on a reply to a post, up to 10 per post.
So, trying to add pictures to post #1 won't work, but on a reply it will.
