the bostons are a 6.5" speaker you could make them fit with some adaptors, but they arent a direct factory replacement, i have two sets of 5x7's in the same for sale ad, thats what i was talking aboutwould the boston fit in my mustang
the 5x7's are called fg i believe, not really sure of the brand, but when i was using them i never had an issue with them, thought they sounded great, as for making an adaptor for the 6.5" bostons, as long as you have enough depth to so so, i wouldnt think makning an adaptor would be all that hard, trace the factory speaker on to a piece of mdf then just out out a 6.5" holewat kind are they.and how hard would it be to make a adapter or buy one
