They might work but theres only I believe about 3-4mm of thread on them.
Whats the part number ? 5318X 5319X ? I can mail you a set to try befor eyou go buying some.
Another thing, it might be kinda had to make adjustments on them since theres no hex on them to put a wrench on.

Either way, let me know dude if you want to try out a set. If you end up buying some and don't like them or they dont work, I'll buy the used ones from you. =)
