I did not search, so bitch at me all you want, as long as you have a possible answer when your done. aside from the obvious 69' to 72' and 73' to 75' coverts. Im talking 76' and up. is there any differences? I only measured the length of the door skin itself. my blazer is a 73' and my burb is a 89'. they both measure bout 42 and an 1/8 aprox. will the full top blazer/burbs of similar years doors interchange? any info will be apreciated, thanks.
