That's the spirit...!
In too many systems there are complications that can turn a good idea into a nightmare, but with common sense and out-of-the-box thinking, one can find solutions.
Saying "Can't" never got humanity one inch further along the road.
Easye1, what else did you come up with?

Hi Kano..
As I was always tinkering with bits from about 10 years old, I made up motor bikes from stuff others had thrown away.
This was the late 1950`s ..
had a nice german scooter stripped, sprayed and rebuilt all ready for when I was 16.
My 2 hands taught me how to do what I wanted from then on really..
I built a drag race car, then later stock car racers,
Banger racers, then back to scooters, then found I loved Landrovers.
To me there Is no can do,
only sit down and think,
"how can I get out of this easily, or/and make a replacement"
My Disco 1 tdi cam belt change needed holding tools,
so i just measured up, and cut them out of checker plate.
The big engine bolt socket, I made from an "Inperial" sized socket that fitted well, welded to an old broken 1/2 inch ratchet, then welded a steel tube round the outside on the socket for strength.
I used a length of scaffold pole to undo then do up again with no problems
In the past i had a beauty of a car, Honda Legend, but the damper/ front pulley was 2 piece with cast rubber bonded, which came apart.
So i slackened belts off, made 2 foot long extentions to go on tapping drill, then clearence drill starter, then a No. 2 tap, and drilled & tapped 3 equi spaced holes through middle on V belt groove in pully while still on car then locktighted 3 grub screws to hold it all in place.
Re tightend drive belts, started engine, job done.
All done without taking anything off the engine,
all working above the radiator top line, a hard job made easy!
Still holding together with new owner...lol
Must be more,
will have to get my tired old brain thinking..
A friend who had a 1800 automatic Leyland Marina with a badly worn starter ring gear welded to the flexi plate...
simples,
chalk marked position of ring gear,
put the starter plate in a 3 jaw chuck on a big lathe, a sharp V pointed tool cut out the original welds, done this both sides,
laid on steel bench, turned worn ring gear 90 degrees round,
re welded it back to flexi plate, placed back in engine, replaced gearbox & starter, perfect.
No matter where engine now stopped, the starter engaged on a "good" section of teeth...
I hate digging deep in my pockets then paying out money,
If I can engineer the problem away,
It keeps my tired old body going...lol
