dana 60 front spring lift

[DetroitDan]

I got a used 4 inch lift kit, guy told me it was for a 1 ton, but come to find out the front springs are considerably narrower than the stock ones. Already installed the rear lift blocks, so I'm kinda stuck now. I don't dare put these springs in, presumably they're for a 1/2 or 3/4 ton. Problem is, everywhere I look online at lift kits and lift springs, they either say it fits everything or it says for 1/2 and 3/4 ton and doesn't mention 1 ton. I am fairly certain I am not the first person to lift a truck on a dana 60 front, so somebody must make a wide lift spring, right? Any thoughts or suggestions on where to find them? I've looked at all the usual suspects, but I am hesitant to order something and end up with the same springs I've already got. Or am I supposed to change it t othe narrower springs? It looks to me like they'd be trying to move around on the axle.
