Those come in such different shape and sizes, you might want to make a drawing for what you are attempting. I made a recumbent trike 3 years ago, and I used Heim Joints to hold the suspension. If you get them with female ends, you can do a lot with them. The mounts can be used to orient them if that is an issue. Heim Joints can be used for many things and they can take a load in virtually any direction. Though tension is probably the strongest. They come in all types of sizes, from absurdly tiny to absurdly huge!
