No they are a nightmare, mine same as you was held up with cable ties especially where they meet inner wheel linings
Gave up and bought a new sheet metal undertray from Adrian @ Torqen best thing I ever done, perfect fit and come with all new fittings
You will get hacked off with the old one lol it done my head in, all my bolts nearly sheared when I removed It totally to replace with the new one
Good luck and try plenty of WD40 and wait a while
