Hobie237 on here needs a set of u-bolt/spring plates for his K30's 14FF. I know someone has a set or a dozen sitting around.
but I think the last one I dealt with was the bottom mount style. My memory gets kinda fuzzy when I have owned over 500 trucks in the last 20 years though.
I thought all 1 tons had the bottom mount setup? Top mount u-bolts can bottom out on the frame mounted bump stop bracket.
I have seen both, but the only ones with the top mount are probably either swapped or didn't have the overload springs on top of the main pack.
