I marked the places where I wanted holes then took the wooden bases out, drilled holes, and installed t-nuts made for wood so the bolts come in through the bottom. The covers are just stapled on; easy to R&R. Make SURE before you drill your holes through the floor plates that the seats will be angled properly and, on the passenger side, will leave enough room for an E-brake handle should you decide to go that way. If you screw up the seat base bad enough you can fix it with a new piece of wood; other things, not so much.
