i've read the post about Si sway bar vs. Type R bar. i've decided to just stick to the Si bar. my question is... since my 2000 ex already has a rear sway, do i need to buy all the other components such as the bracket, bushing, clamp, and endlinks for it? or can i just use my stock and just replace the sway bar with the Si? btw, how thick is the regular EX sway bars? i know the Si is 15mm, but what about the stock EX?

here is the break down of the parts pricing from www.parts.com

Si sway bar $64.08
bracket (2pcs) $17.88
bushing (2pcs) $6.46
clamp (2pcs) $7.66
endlink (2pcs) $86.22
total $182.30
