Thanks mate, I'll wait until she's back up and running without any clunks or rattles before I pass judgement on that
I think this video is where I heard that bit about the guide tube, from about 5 minutes in. Made sense, and I'm glad I did it looking at the condition of the old one. Cost $80+GST from the dealership. I did have a bit of a squeaking noise when pressing down the clutch previously, pretty faint and nothing to be overly concerned about but now with the new tube in it's perfectly smooth and quiet. The DSSR also seems to have gotten rid of some slop in the linkage, the shifter used to have more side to side movement when in gear, noticeably reduced now.
Bit more progress from last night. Engine bay and front end all put back together and buttoned up. New oil filler cap - was cheap as chips, and not repping Castrol anymore.
Also, finally replaced the front air duct that had been missing ever since I got the car, although it "didn't need one" according to the PO...
Impossible to find these in good condition second hand or at wreckers nowadays so got a brand new one through the dealership. Having that extra bit of access did come in handy at times but does make the front end look more complete without a gaping hole right behind the bumper.
Front subframe also got a bit of rust treatment and a few coats of paint whilst being dismantled, tidying up the underside quite nicely.
Suspension reassembly next, finally.
