I wouldn't drill through the frame.The frames are pretty light and you run the risk of collapsing it,unless you also put in a weld in tube spacer. I did the same as Kurtis drilled and tapped the frame for 5/16" bolts,and it's pretty stable,if you manage to rip it off the frame,you've got bigger issues to worry about,lol. One thing wise is to upgrade the fittings and hoses to -10 (5/8") from the -8 (1/2") hoses and fittings supplied in the kit. By the looks of it you're running the stubby filter,you can go to the 30-8A RP filter for a little more capacity. Mine takes roughly about a 1/2 quart more oil to bring it up to the full mark
