I tried asking before and got no replies, maybe I'll have better this luck with this thread. It looks like the late model parcel shelfs take a 6 or 6 1/2'" speaker instead of the horrible 4X6 in the early cars. Will a late model shelf fit an old 126 and what year did they change. I think a pair of 6 1/2 would fill in the bottom nicely, I have a 10" sub in the trunk and I have to set the crossover higher than I would like because of the lack of bass that the 4X6's provide.
