Yes. The EcoHitch # EH75FR will come with detailed instructions for you to follow along with during installation, including where you'll need to trim on the underbody panel. You also can likely avoid the cutting by simply removing the underbody panel altogether. view full answer...
If you check out the picture I attached you can see that the knurls of the wet bolts like the part # 126B2 are supposed go through the shackle straps and not the bushing. I believe the issue you are having is you are trying to force the knurls through the bushing. You may need thicker straps if yours are too thin to prevent that. view full answer...

This is the replacement leg portion without the motor for the front of the setup like you are needing. Lippert does not offer repair kits for what you have. view full answer...
