Here are some photos of FE vs EK seat surround mounts, in response to this thread in 'Parts Wanted' (I thought it more appropriate now in this section):
http://www.fefcholden.org.au/cgi-bin/yabb/YaBB.cgi?board=pwntd;action=display;num=1128921577I should start by saying that I 'think' my FE seat is an FE seat. I was a little confused by the fact it has a rear ashtray mount and I have a ute....but folks seem to think this in just a mass produced item. Anyway, as far as I can tell, the only difference between the two is that the EK seat is about 4cm lower in height and has slightly different mounts for the seat surrounds.
The front mounts are identical:
The rear corner mount is slightly different:
and the mounting point on the rear vertical is in a slightly different place:
All you would need to do to fit a metal EK surround to an FE/FC seat would be to grind off the tab 'A', fabricate a tab 'B', and then add an extra plate on the vertical to screw into. Here is the EK surround fitted:
hope this helps.
