No attachment points on the chassis. I used lots-o-glue where the frame meets the floor pan. Ignore the instructions and attach the bumper mounts at the beginning (especially before the gas tank is mounted), otherwise you’ll have problems clamping them in place while the glue dries. The instructions show steering linkage for the custom version, but no mention of it for stock. Also, instructions mention stock lever action (torsion) front shocks but not how to attach them (I eventually figured it out).
