Kits for these would be tough to make mostly because, even after all the pieces are cut out they still have to be pre-fit and then sanded and adjusted to make it as close to perfect as possible.. a basic kit could be made but take it from me, ive made so many of these and i have gone through the "trial and error" stages so somebody like myself that has built a few will know what to expect and not be taken by surprised.. .. last thing you want to do is put a little money into a kit and then ruin it by mistake cause something caught you off guard... just my take though. Whats better than a "Kit" would be for you to just start experimenting with making your own..
