I see Mazdatrix lists a different PN for a NA and TII trans crossmember. I have one of each side by side. They look the same (except my TII one has a thrashed center bushing) My guess is the rubber is stiffer or the TII? Would I notice the diff if I used the NA part on a lower power build?

 

only difference I could see is the body mount holes are at the other end of the slotted section. oh well I have two NA and one TII crossmember and there all trashed in the center hole bushing. Is there a better product or mod to make that area stronger?
