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! :confused:

Under the seat will be very different in an 07. Ive got an 03 and my dad has an 05 and he has less than 1/2 the underseat space I have

Dont buy prefab, Ive never seen an 07 so I cant help though
