Kind of Saw\'s??? Hey all...I'm starting to do the rear panels in my 86 Blazer I'm going to do them out of 1/4 or 1/8 inch oak ply wood and stain them..I also want to add speaker holes by the rear passenger seats..(sort of like Broncos)? And in the back like the stock panels..I need to know what sort of saw(s) I will need to cut the holes( about 5 1/4 inches to 6 inches) perfectly circular, and also the bend for the wheel wells, and maybe even oval for 6x9 speakers(rear) Thanks for the info!! you all rock!!
