searched a bit and some things were covered but couldnt find others

i know that cat back exhaust are same for sedans wagons lwb (EF/Ls, NF, NL's) up to the tailpipe piece and then they'r different. but would pricing be any different too?

also these pacey extractors on ebay.

http://cgi.ebay.com.au/Ford-EA-EB-ED-EF ... dZViewItem

they say will fit the E falcons etc and fairlanes up to NC-ND.. but not NF NL..
i dont know whether to take that as theyv just missed them out and they do fit. or that they'v left them out on purpose and DONT fit..
i messaged the seller but no reply yet.

who will be a darl and help me

The extractors will fit, not sure about pricing differences on wagon and LWB systems.
