what are these bushing for and year wise
 

the numbers are:

14008366 (???)

3893159 (upper core support bushing right)

i found them in a coffee can in my garage
while i was spring cleaning.

also i have a fiberglass L88 hood that is a lift
off hood with with hood pins(corners need some work)
is it worth anything or garbage.(67 to 69)

thanks for your time and help in advance
