don't get me wrong i think most of the lwg had the flex tubes. but the first and only set of hard ones i had ever seen was on larry davis lwg from alabama. this car has the second set i have ever seen. if i remember correctly the very first few cars had these. i know when i asked about larry's dennis said they hunted foreever to find his. like i said these are the only 2 cars that i have ever seen them on,but they are correct... if dennis reads this i'm sure he can explain the application much better.......gopher
