The front suspension conversion on Big Blue uses a Sky's kit. And my experience with them in doing that conversion was both good and not so good.
But to be fair, I got their very first kit to put a D60 solid axle using SuperDuty springs in a Bullnose truck. Erik at Sky's had installed the prototype but made changes that didn't work out as planned. So when I got my kit the crossmember wouldn't work. He and I talked frequently and he made the needed changes and had a new one made and shipped to me. And it fit perfectly. But I was hung up for a while waiting on the new part.
However, the parts themselves are well done and the fasteners are top notch. So I would buy from Sky's again if I were in the market.
