Bolt in frame connectors

The problem is not every car is the same. That's why they make them with extra material so you can grind them to an exact fit.
Bahahaha my point proven again! LOL you still have to make them fit and grind on them and then weld them oh my God! That's not even right! So once again I'm better off making my own cardboard cut out of the bottom of my own car and basically making my own?
