I just saw your post from last year about the Dale Jr. GM concept spoiler. Did any of the guys get back with you about having that same spoiler? I messaged the LoneStarClassic guy yesterday that has it posted on ebay (the same link you had)and asked him what the height was of the spoiler as if you were standing behind it. He replied today and said he doesn't have the car to measure the spoiler. Thought it was an odd reply. Let me know if you had any luck.
