If you want to use bolts (and I can't see why that wouldn't work), I would use shoulder bolts with a long enough shoulder to make it through the whole hinge, and cut the threaded part down so you have just enough threads left for a nylock.

Melle that's what I was thinking.
I have some stainless shoulder bolts.

Melle, aye, but my whole point was that the UK Amazon site tells you all the nasty things, the US site does not.

Right, this got postponed as we were moving house but decided on the run up to Swedish Day to get it done.

Just did the upper one but the bottom should be the same process with a different size bush and pin.

First hurdle is getting the hinge assembly off the car. I found an air powered rattle gun did the job quite easily and I know these have never been off the car before. For anyone put off by the hassle of air tools I'm using an Aldi compressor which was half price and a Machine Mart rattle gun. This has proved extremely useful for jobs like this and particularly getting nuts of flywheels as trying to lock them in place is a right pain. This just goes bosh, bosh, bosh and off they come.

Next up was separating the two parts and on the original proved a massive headache. I had a spare which had a bolt in place of a pin and this came apart ok. Ended up using the original fixed part but had to really make a mess with the swinging part so used one off the spare.

Then drilled out the swinging part of the hinge to 12mm and pressed one of these in https://www.ebay.co.uk/itm/112746807327?var=413198535096



The remains of the old pin came out ok from the fixed part and that allowed a new pin from Malbrad to drift in smoothly. Overall a very satisfying job but still need to do the lower one and both on the other side.

Question: Something I had never noticed is that there is a removable rubber cap to allow grease to be injected. I was tempted to drill the oilite bush to allow this function but as I understand it oilite bushes are self lubricating so decided not to. Thoughts on this would be welcome!

Hopefully big updates soon on the 96 as went to North Wales last weekend...

Cheers


Does drilling out to 12 mm, not weaken the hinge part? ie not much material left around the 12 mm oilite bushing.
It is my preferred option, though as per conversation with Melle, am considering just using a S/S M8 shoulder bolt.

Andy, if the problem is worn holes, just replacing the pin will not sort the problem without fixing the holes I suppose? Gareth's photos suggest there's plenty of meat to fit bushes.

Melle
I've ordered the bushes, and will have a go!
I've got plenty time. My welder is going to be a while replacing my door bottoms, and the paint man can't do the paint job till January.

I also bought M8 shank, shoulder bolts, with M6 threads, 30 mm long for the bottom hinge, and 40 mm long for the top. These lengths fit exactly to the millimetre!
High tensile steel.
Available here from GWR fasteners:-
https://www.ebay.co.uk/itm/271319010373?var=570212542813

I've done the lower hinge first. The hole in the swinging part was not worn at all. The above shoulder bolt, M8 diameter, fitted it perfectly, with only a slightly perceptible play. The end plates was where the problem was. Slack as hell,
So drilled the holes out to 12 mm. sliced the oilite bush to give 2 thin bushes to go top and bottom, and Bob's your Uncle!

Assembled with grease on the centre pin, to the swinging part, and oil in the bushes.
You can see the bronze bush in the plate, top right.


Assembled, ready for paint.


The upper hinge bushed as well now.
Great idea Gareth.
