Go get a piece of 2x4 tube steel use a piece of cardboard to make a template of the floor trace it onto the steel and cut it out. It will cost you 1/10 the price of what they want for the ones that are already cut out and you will have them welded in in half the time. I bought the X5 ones and spent 10 hrs fitting and welding them only to realize that I spent $200 for $20 worth of steel. OOOOHH but their LAZER cut that would be great if they FIT. The X5 frame connectors are a JOKE.
