OK guys...I'm attaching a couple of photos of our air filter housings. We have filters but, other than those, these are all we have. Looking at page 114 in the VictoriaBritish catalog we appear to need a whole bunch of other stuff like #9,10,11 & 12. We can't tell for sure. Of course we have the bolts to hold them on.
Housing on right is front. Can you see the little tab on the rear plate? What's that for?
Also, if those two springs don't go where we have them, where DO they go...we don't see any other option.
