I have a first gen. Correct me if I am wrong but this will go from 04-08. It will fit the E-Tech II, or more specifically by the GM production code, GML91. If I have a large (5+) number of inquiries for the second gen, with the Eco-Tech, I may consider designing one, but it may be a challenge since I don't own a second gen. I want to complete this project first before attempting another, but I will certainly consider it if enough people really want it with cash in hand.
