Does anyone know where i can get longer torsion bar bolts?

I bought the ready lift kit and it came with the right keys and bolts but when i took it to the shop i think they kept the stock bolts in there because i can pull them out and pull ones out of my moms tahoe and they are the same size but the ones that came with the kit are longer than the stocks.

I'm not sure of where i can get them so any help is nice

 

best bet would be call around a local shop that does lifting and stuff.. they should be able to tell you if they are longer..and they might have sum they can give u or sell you
