sparco bucket conversion into 69 chevelle bench seat car

[pt2285]

so i have the sparco brackets and it all lines up nice, but my car is a bench car so i need to drill through the floor for the inner mounting bolts. for safety i need to add some metal for those inner mounting holes. AMD has the weld in brackets and they are cheap but since im already level, can i weld some good thick metal to the underside of the floor pans to add strength?

The bracing and floor is the same from the factory in bench and bucket seats cars , the only difference being the factory mount welded on top of the floor inside the car

exactly but for safety i cant just drill through the floor, sink a bolt, and call it a day. so if i add more metal to the under side of the body, is that ok?

It is best to use the factory mounting holes as these were the locations that the seat belts were mounted and tested.
Use seat belt anchor plates if you must relocate holes for mounting.
