Also, there were crimped top nuts, which on casual glance look like nylocs.They've been around since before nylon was invented. Simmonds nuts had a fibre insert, similar to the stuff fibre washers are made from.
If they are on long enough to rot the plastic the rust will be holding them firm, don't worry. Putting threadlock on is defeating the object of the nyloc, why make them twice as hard to remove ?That will make my life way easier! Thanks.
Does the plastic in nylocs break down over time?
You could go "old school" Castle nuts and split-pins.

re the shackles standard practice on the front axles of lots of vehicles
look at the damper units . ones fixed at the rear and one at the front who drew that lotI think the shackles are at the rear - look at the orientation of the diff housing. I suspect the labelling is wrong. FWIW some cars with tourque-tube axles had shackles at each end of the spring.
Remember to buy the correct grade of nut to match the bolt. In the same way as bolts are graded. i.e. 8.8,10.9 etc
