Yeah its all laser cut and then Denny tacks it together. I believe he leaves the rack mount loose so you can set it at optimal position for your engine combo but I'll leave that to the man to verify. Denny also offers the thing fully welded but since my buddy is a tig welder by trade I decided to save a few bucks and ordered it tacked. I also haven't done engine mounts on mine so I can put my engine wherever I need to once I have the k installed. This is a very unique set up from Hemidenny that Cody and I both spent time checking and double checking so he had all the measurements he needed.
