More time spent at the barn today
Firstly removed the horrible seats out the MX5:
Crap lighting in the photos and it doesn't show up the filth on those seats, or the wear and crap repairs.
Then I got about fitting in the replacements:
Much better looking imo

Comfier too, and the added height of the seat adds a pleasant false sense of security (I'm 6' and the head rest not reaching my head height made me constantly aware of the fact that if the car rolled my head would have a one way ticket into the tarmac

).
No modification was needed to fit the seats even though they came from a later car - the runners used identical mounting points.
I even found £3 under the driver's seat, which paid for the cheese burgers at lunch time
Meanwhile my Dad was at the barn with me, as his latest truck needed new front pads & discs:
Yep, they appear to be toast

Not good.
New stuff in place:
It was a bit of a learning curve replacing the discs on this, as you have to remove the free-wheeling hubs in order to get the discs off. This involves removing the wheel bearing which is a bit of a pain in the arse. We got it done though, with a bit of logical thinking and a trip to Halfords for an impact driver (the stress relieving kind that you mash with a hammer).
@thebusofwoe, one question that you might be able to answer for me - how important is it to torque the 'nut' in the pic below:
My dad was happy enough returning them to the position they came from by eye using the markings, but according to the interwebs you need a special tool, and have to do it up once, back it off, then do it up again

Should I send him off to the mechanic to get that done properly? It has a locking washer on top, and we took a fairly vigorous test drive around the yard during which the wheels didn't fall off, but it's in the back of my mind...
All in all though it was pretty constructive for a Sunday, especially as I have an exam in the morning
