It is a buddy's base, it came with his AAR Cuda and he wants the correct base.
It appears he may need the lid with the wide lip too.
I'm sure both pieces are wrong, He has an engine for the AAR but not the original one, but it is a T/A-AAR engine. The car hasn't been out of the garage in decades, and the Demon GSS he has might have been out 10 years ago...
