I did a 120 y dash pad on my moms car and all I did was to sand and fill the cracks with silicon.After doing that I then had to trace the hole pattern of the radio speaker holes.I did this by masking taping a piece of paper to the old dash and poked a pencil in all the holes to Aquire the pattern.I then glued 1/4" 6 mm foam on it but I transferred the hole pattern to the foam with an art line felt pen. I did this to the vinyl too to punch out all the holes I used a small single hole punch , block of wood and hammer.I glued on the foam with contact adhesive lining up the speaker holes. next the vinyl was stretched over the pad. I managed to do this with one piece by stapling and glueing it on the underside of the pad. It is very difficult to stretch vinyl like that but carefully using a heat gun and vice grips you can stretch it.1600 / 510 page would be far easier. Your other method is to cut out patterns and sew in seams and recover it .Lots of guys in the 70's and 80's used that crappy looking fake furry sh*t and contact.Thank god that has gone out of vogue these days.Only a minor concern really for me but if you don't have the knowledge or skill then you just need to pay for one.
