As for bolting it up everything was great except for one lower K-member mount that was very close. It took just a dremmel to match it up. I think it was due to my car though. I really like the complete package(mine is for road race). The main problems I had were with the D&D hardware,which some just didn't fit and other parts were not threaded correctly. I had to drill to get a bolt through for the steer rack. Not a big deal but for the cost of the package you shouldn't have to spend $5 more.
I have a built 351w to go in but have not done the installation yet. I will let you know how it goes. Overall I really like the system.
