In order to use the short stud with the Lump you will need to Open the hole up on the lump. The head of the short bolt that comes with the Lump kits are of 3/4 dia. and use a alien to tighten them. The stud kits have a Nut So you'll need a socket to fit in the lump hole. And I believe the nut is a 12 point.
God doesn't like ugly.
