12. Q: What is the GM part number for the Grand Sport Hashmarks decal & its dimensions?

The GM part number is 10279781 (GM LIST: $39.57), listed at "STRIPE, F/FDR WHL OPG" and each stripe is slightly different. The left (front most) stripe is 2-13/16" wide while the right (rear most) is 2-11/16" wide. Each is approximately 8-7/8" long and they are spaced 3/4" apart. Torch Red is a perfect match in color.

Note: As of 10/07, this item is still available from GM but in limited supply.
