So I bought a 73 challenger today, been wanting one for 30 plus years. Found it in OK shape, everything seems to be there. Except the engine, and maybe some other minor parts. Here's my question, as a newb, but someone who has been reading up on the 73 challenger.... This car has the correct fender tag (matches the VIN how it should), and I see an A57, so I want to assume this was a Rallye, and the engine was originally a 340, according to the VIN. but there are no side scoops on it, and the dash gauges are non-rallye. Do you suppose a previous owner changed the dash gauges ? What else could I look for to determine if this was originally a Rallye. Or does the fender tag alone suffice? Thanks
