I could not find a match to my 81 grey dash in SEM. I did find duplicolor vinyl and fabric in Charcoal Grey hvp111 to be exact match however. I refinished the upper and lower dash but left the console original. I can see no difference between them, and yes it does have a bluish hue.
I wanted to share some photos. Of the new Legendary Upholstery I received through Chuck Sharin for my 81z. Chuck spent a lot of time with this order due to availability issues with the cloth inserts but the results were well worth the wait! I would recommend Chuck to anyone looking for...
On my silver custom cloth interior, I used
SEM 15123 Warm Grey for the light grey areas
Dupli-Color hvp111 Charcoal grey for the dark.
Both were an exact match. The dark grey does have a slight blue hue. BTW I could not find a dark grey match in SEM.
