You know, the old shaped plastic 'bottle'. Where is the best place to purchase one? It's for a 70 Cuda.

I bought an A-Body one from Mancini that was perfect after buying one from someplace else that was not a Chrysler licensed reproduction. The first one that I bought did not fit because the mounting holes were about 3/16" or so too far apart meaning I would have had to slot the hole(s) or make new ones. I was not about to do that so I bought the 2nd one from Mancini to see if it was any better than the first one, and the holes on it lined up like they are supposed to. Try to get one from someone who sells the licensed ones if at all possible.

try mega parts in Wisconsin i think .

Isn't a '70 a split year for design?
If it's important there is an early and later style.
