I am wanting to order a Z51 2LT with Brownstone interior. I understand the D30 override will let me do this. My question is which interior do I get? A 2LT or a 3LT since Brownstone is only a 3LT option. Please let me know. Thanks.

D30 only lets you order a color combination that GM does not "approve of". For example, the red interior with Laguna Blue. Brownstone is only available with 3LT, so you must order 3LT. D30 will NOT let you get a 2LT with Brownstone.
