my car ,being sold in Wisconsin ,but been in Texas for at least 14 yrs...no windshield movement (sometimes I wish there was,its sooo hard to latch!) , didnt have the X brace when I bought it (removed to "help" install non correct exhaust), I bought from Ames , think it was $80, easy install...4 bolts...

I dont have subframe connectors, car seems fine w/o them (and I dont drive it like grandma!), even though most my friends have them and swear by them...
