Part Number Confusion

[moparpjf@xxxx]

Hi Group-

Now, I might not be the sharpest crayon in the box, but I thought I 
knew how to read a parts book. Now I'm not so sure.

I have a number of what are obviously 1960 Chrysler tail light 
assemblies, but they have varying numbers on them, so I consulted my friendly parts 
book to see which were which. The picture in part 23 tells me that the 
housings are "serviced" in 8-55-7, so I go to 8-55-7 and find none of the numbers 
appearing on the housings.

The numbers on the housings I have are as follows:

#1960908, 1960909 and 1960798. Somewhere I think I have a 1960799 as 
well. I cannot find any of these numbers on the parts book - can someone help 
me out here? I know the even numbers are right side, but why aren't the 
other numbers there? All my numbers start with 1961. Could I have a very late 
revision which is showing the superceded numbers?

In any event, if someone can identify these for me, I would appreciate 
it very much.

Thanks,

Pete Fitch
