Hi Matty.
You have both the colour & trim codes there, note the reference colour over trim to the left of the code
002 is your colour code named Blanco
The trim code is C for brown trim

kegs,
I just ripped the m/cyl off the ute and checked the clutch cable placeing.
It clears the booster with plenty of room to spare.

kegs, it seems that way.
I haven't done it yet but looking at & measuring it itlooks easy.
You will need to drill a few holes to mount the booster.
You may also need to move the clutch cable a touch or atleast pivot it around a bit so there is some clearance from the booster.
I hope to be doing mine in a few weeks so if you need I can advise better after hands on.

I have a 79 Sunny & 85 1200ute
the Sunny M/cyl is the same except that the bore is 13/16 and the ute is 11/16.
The Res for the front is also a little larger to accomodate for the Discs.

If your rubbers are not too hard or perished (like mine ) then you can usually get them out without cutting them, just needs a little care.
Mine didn't have mouldings so it didn't matter , although the new rubber I have in has the lipping on the outside to enable mouldings to be refitted.

A professional can do a clean (no substrate damage) ordinary external respray in about 40 hours.
As Team_Dat says three quarters is Prep mostly rubbing & cleaning, rub & clean, rub & clean, rub & clean.
Always get a quote & try to see some of their similar price point jobs if using a body shop. Ensure what you are paying for is what you want.

Does it sound like you are choking it??
use less choke

That is correct... (ie less turns lock to lock ).
I don't know about actual turning circle, I am off the road and can't compare the 2.

There is a sad wreched demented animal trapped somewhere behind that mask.

Sounds more like a blockage in the delivery (of oil) .
It sounds like a problem that wont go away without a full work over to find the source then fix it and subsequent damage.
