Personnaly, I'd use a dash cap rather than a plastic core dashpad. You would also want to see the new pad in person or maybe someone on here could respond. Is the metal core of the repops a very thin, flimzey metal ? I f so, you are no farther ahead .
After researching this for months and talking to owners on other forums, I decided to have the original pads from my 68 Barracuda recovered at Just Dashes. Yes, it cost me over $1000.00 US. but my rationalle for doing so is that the dash is one part of the car you will look at constantly while using the car. I did not want to look at a pile of crap dash pad while Im trying to enjoy the car.
After going all in on everything else for the car it would just piss me off .
