The dash in my 1980 280ZX is cracked in a number of places. Do any of the overlays fit properly? What options under 2K are available?

The full dash cover is about your only option aside from a place like JustDashes which will cost 10x more plus.

The covers fit well as long as proper prep work is done to assure good adhesion.   Only other possibility is sourcing a crack free oem dash...  (could be tough to find)
