'77 corolla wagon, corroded cylinder head lost its cool half way to Geraldton, rolled into a roadside parking bay and under a nice shady tree.
Ripped the cylinder head off and found the ally head had a hole a tad smaller than a 5 cent piece, which bridged a coolant passage and the head gasket.
I scraped out the loose corrosion, hammered in a 5 cent piece, added some gasket goo and put it back together.
I had only had my license for a week or so, and that was the first of many dodgy-ish roadside fixits.
Traded the Corolla for a V6 Capri a year later, then the fixits became even more regular.
-------------------------------------
Capri's dizzy fell to bits on the way to Albany.
Found a dead transit van in a farm scrap pile.
Used the dizzy housing from the V4 transit, and hoiked in the V6 dizzy innards - up and running again.
Capri timing gear fell apart, bending a bunch of valves.
Scrounged a timing gear from another V4 transit, and valves from Datsun engines.[all from Toodyay Tip]

Capri gearbox failed, [many times] over the years I used bits from transit vans, [same cogs, different shifter and extension housing], Cortina's [same cogs etc],
zephyr [same cogs - but mirror image housing]
--------------------------------------
LJ50 'zook with LJ80 motor, using the '50 radiator and exhaust - constantly overheating, so bolted the external oil filter bracket from a burnt out slant 6 Valiant on one side of the front bumper, with a Volkswagen oil cooler on the other, silver soldered barb tail fittings onto everything, dodgy-ed up an adaptor block that screwed onto the motor and piped them all together.
More than doubled the engine oil capacity and all the overheating ceased.
---------------------------------------
HQ 1 Tonner, radiator holed by a roo's leg bone / fan stuffed.
Crimped the damaged tubes with pliers, but didn't have enough water to refill the rad.
Jumped a fence and walked to a dam for some water, still had a slow leak - so left the radiator cap on loose so it slowed the leak down, topped up the Rad every few klicks - until I noticed that the sediment in the dam water had blocked up most of the leak.
Used the washer pump to squirt water over the radiator to help with cooling whenever the gauge started climbing.
---------------------------------------
The fuel pump carked it in one of my Fiats - leaking petrol badly. [later found to be a counterfeit pump]
Bypassed the pump with a biro housing, hooked a 12 volt tyre pump to the fuel tank vent hose and used air pressure to force fuel from the tank to the carby.
--------------------------------------
Brand new Toyota Crown at the hotel I worked at was broken into - smashed passenger window.
No spares in the country. It was a Saturday afternoon, Boss was worried - the owner was a bigwig running a medical conference at the hotel.
It was middle of winter and bucketing down, the Doctor that owned the car was not happy.
I nicked the Perspex side from an icecream fridge in the Brasserie, and made a temporary window so they could get home in the southwest without drowning.
----------------------------------------
A Scout Association owned Lada Niva [that had been seen "swimming" for an extended period of time at Lancelin] was dumped at the property I was working on
[The property was supposedly being donated to the Scouts]
HQ reckoned I could use a spare 4wd on the farm.
Nice idea - if the thing would run!
Found that the emission controls and fuel system were full of salt water and mud - as were the diffs, transfer-case, gearbox.
Drained all the fluids / flushed with diesel / refilled with fresh tractor grade stuff [since it was free].
Emission controls and all the fuel system were removed, blown out with air and the good bits were replaced.
Simplified the whole system - not exactly ADR compliant

using none of the emission controls, and jamming .303 cases into the air cleaner housing for the "new" carby breather and crankcase breather thingy connections.
Removed practically all the wiring and anything not deemed essential, since much was salt water affected.
Damn Niva went like the clappers after I put it back together, and was a great little runabout on the farm!
