I bought Eaton Detroit Spring 5 leaf springs. They were the correct leafs for my application. I also had them add a 1" drop over stock ride height so they would sit lower. Eaton isn't a one size fits all type of spring company. They actually use the original GM blueprints to create there leafs/springs. They fit great. I also bought their leaf spring installation kit which has the shackles correct bolts or U bolts, various pad to install the leafs. You can click on the link and see a picture.
