So the retracts come preinstalled with wood screws. I have two issues with this. First I do not like wood screws. I like Dubro bolts and blind nuts. Second, as delivered, the position of the retract caused the wheel to not fit inside the well in the fuse. To correct this, I needed to relocate the hole location for the retract bolts. This is accomplished by epoxying in hardwood dowels and then sanding them flush with the retract mounting rails
