No, I don't want to buy a prefab! My friend wants to keep the jack under the seat. This is for a CVT12. If you have a prefab, measure it. That will give me a good idea of how to build it. I found one box plan but it was for a 2003 and I think they might be different under the seat. Someone please help! //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
