I have a buddy that is a awesome welder and fabricator.He works on the side out of his home and prices are very reasonable. He can build sliders for around $300 or less. So anything you need done big or small he can do it,I drew up some pics of dual swing out fuel can carriers, it took a total of 2 weeks to get them done but we both work full time jobs so we only had a hour or two after work and most of the weekend and this is how they turned out.
PM me and I will give you his contact info
