After searching I found a thread that says you can use 79-85 mini ps boxes for a conversion on a FJ40, I have everything except the box, So I am in Seattle and call around looking for one, the guy at the yard says that 79-80 are one box year specific and $265 and 81 to 85 are the same and $150. This is just the first yard and will have to wait until monday for him to reopen, but I'm confused is there and difference and are these the only ones I can use ? I hope someone can clarifly. thnx Myrle
