Harness bar

Does anyone know where the cheapest place to buy harness bar and 4pt harnesses is? I want a bar that does NOT interfere or replace the stock seatbelts. I need to have those to buckle in the little angel's car seat when she starts out on the trails with us, but I want to be able to use better harnesses when adults are riding in there. I have seen them on ebay, but most bolt into the factory seatbelt holes. I did see one months ago that bolted in right at the bottom of the stock seatbelt mounts, and it did not interfere and you could use both. I be damned if I can find one reasonably priced now. I think that one sold on ebay for 125 or something like that. Do you all think these belts could be secured in the stock holes right along with the stock belts? I can see how the shoulder part mounts. I am just curious if the "lap" portion mount could be used in conjunction with the stock belts.
