Find a spring shop or a big truck shop locally to make some for you. The vatozone jobbies would be a last resort if you driver your junk on the street a lot.
Auto Spring co. in Winston-Salem can make about any size you would want, but it would be a good drive from Trinity. They normally charge about $7/ea, but you can pick whatever size you want, mine are 5/8" I think.
Fleet Pride in garner does over here.. Same deal tell them what you want they make em on the spot.. Make sure you get the special wide nuts and hardened washers..
It says you're in Trinity... it's worth the ride to Fleet Pride in greensboro to get them done. They've done a few for me, and they do a pretty good job with having the sizes in stock that you need.
