If your inner rocker panels are solid you won't need any bracing, depending on various things I'd say $1000 bucks would do it at my shop maybe a little less. The main problem when someone asks for rockers you end up [a lot of times] replacing A and B pillars and inner rocker panels along with floor patches and possibly cab mounts and also foot well panels and maybe even cab corners. The above poster is correct it is no big deal to do just the rockers but it is the hidden stuff or stuff you can not see until you tear into it.
I did a job late last year the cab had original paint but clearly need new rockers that ended up getting all the parts I mentioned above with small exceptions of B pillars and cab corners. Good luck If I can help you through it I'd be more than happy to. Jim
