I've got an Omori 45mm mechanical boost gauge for sale. Comes with pod for mounting on the steering wheel (same as a stock boost gauge), and all the hardware you would need to install, including T-fitting. Tends to read a tad low, but otherwise in perfect condition. $90 obo. I also have a Whiteline 22mm front sway bar for sale. Never used, in perfect condition. Comes with mount bushings. $100 obo.
with adjustable endlinks it will fit, but angles it connects at will be a little wide. The wagon FSB is slightly shorted to deal with the track width difference.
