Oh yeah, well over a year ago now... I had to go through the MA. DEP and use what at the time was a brand new "clunker" process, for kit cars, replica's etc... I think I was only the 2nd person to do it, so it was quite a learning exprience. For the process I used a 73 LeMans 350 as the "clunker" car to junk, so now when my dads car is inspected, it's inspected as a 1973 model vehicle, so, it's emissions exempt.
Read this post from "ffcars", I outlined the clunker process I used to get get emissions exempt by the DEP:
