I have two kits of the Thunderbird SC. I am using the engine for another build. The 1992 seemed OK but the 91 kit seems that the plastic is a bit brittle. Did Revell have aproblem with the plastic in 91? I also have a 1990 kit but have not started doing anything with that yet.
I went to a car show last weekend and they had a few. I will post some more for you. Still sorting them out took around 250 pics nothing newer than 64.
