I have the tools for both these now (thanks). The whitish material - a guy sent me the washers on the studs of 70-71 Duster taillight bezels. Same material. This whitish, rubbery material is also used on the cuda fender gill studs. I found a GOOD functional equivalent material for this stuff; gum rubber sheets.
On that stud above with the whiteish seal, can you tell me how thick that is? Gum rubber comes in 1/16 and 1/8 but I can get 3/32" made.
The white ones Joe needs are easy. How many? Where are they used? ID? OD? Thickness (1/16", 3/32", 1/8"?)
Glad to know I'll be able to get these from you Jim. 
I would have taken caliper measurements of the ones that came off my car, but they are so far from being close to what would have been their original shape. I did not find the thicker black foam washers/seals when I removed the 1/4 trim pieces. I'll definitely need both. The hood trim uses (8) clips; the deck-lid trim uses (2) clips; and the two 1/4 trim pieces use a total of (6) clips. So, I'll need at least (10) thin white foam washers/seals, and at least (6) thicker black foam washers/seals. Thanks to all for the help.
