66 chevelle floor replacement?

[Thenovaguy]

I'm looking to replace the floors,floor braces and inner rockers on a 66 Chevelle. Since I don't possess the skills and knowledge to do it myself I'm checking out local shops. So I'm wondering how many hours it would take to replace. I got one quote of between 80-120 hours. Does that sound right? Most shops wont give a rough idea and say they just work at the shop rate. I have never done such a job but I would assume it's time and labor intensive due to having to separate the frame from the body to access the inner rockers. I would appreciate any guidance on what a realistic number would be.

Thanks
