I have my repacement front speakers and wanted to know exactly what tools are needed to get the dash pad out and speakers in before I tear it open. I also have two cracks in the pad on the vey outside screw holes, next to the speaker grills on each side( looks like they were tightened to tight, caused them to crack) These cracks are about 1-1/12 inches long. Can the cracks be glued or do you get a new dash panel? Thanks in Advance Rick 86 GN
