The thing I didn't like about the job that Just Dashes did for me on my 1971 dash was they left the leading edge of the dash WAY too thick if you look through the front window. They originally tapered to a fairly thin edge along the top leading edge. At Just Dashes they built up this area with new foam but didn't sand it down nearly enough (or at all) to make that a tapered edge. Result was that the leading edge is much, much too thick to resemble original. I sent the dash back to them at their expense for them to re-do it the right way. I think they just sent it back to me without doing anything but told me they had fixed it. I received it back exactly the same as it was when I sent it back to them to fix their work.
This problem they have is so common that 2ManyTA's would frequently point it out to people who have gotten their dash back from Just Dashes.
