Well I sent the springs back to summit today. Waiting on refund then will order some belltechs instead and hope that they're not two different lengths. Also found out I've got two different spindles, one belltech that's supposed to be for a 71-72 c10 and have no idea what's on the other side so looks like I'm gonna have to save up some money for a new set of 3" drop spindles too. Wow, this truck is such a POS! It's looking like every single part on it will be replaced before it's done.
