SPS-170a

Im about to purchase these (Alpine SPS-170a Co-Axial), but every place i look says they wont fit in my car (1995 S-10 Blazer 4 Door). I dont understand why they wouldnt fit, since the door speakers ARE 6 1/2", and so are the Alpines. Could it just be an automation error? If not, what else would determine "fit" or "not fit"? Ebay's automated system also mentions a "OEM Adapter" ...what?

Well, i popped open the left door panel and it turns out the speaker is a 6 1/2". Alpine, here i come.

the depth could be to large...meaning it potrudes into the inside of the door to much...this could be solved my making a 1/2" mounting ring for clearence.
