Bed bob and marlins rear bumper for and 85 pickup

[85Toyotar]

Might be a dumb question but if I were to bob my bed, (not sure how many inches) all that would be different is the mounting holes would sit farther forward (towards the engine) to mount up? Or are the pre-drilled holes on the marlin rear bumper matched up with holes already on the frame? Or do the frame holes get drilled by yourself when installing the bumper? Basically I don't know if the frame already has existing holes for the bumper to go into place.

The frame already has holes, so you would either need to shorten the bumper mounting bracket or drill new holes in the frame to mount it to.

Depending on how much you "bob" the rear..you may have to cut and adjust the wrap around part on rear quarters..
