I've managed to find just one and will continue to look for the rest.

Here is a picture for reference;

i was able to buy some at my local hardware store earlier this year when i needed some.
theyre just a fine metric thread like m12 x 1.25 although i cant remember exactly.
take that one as a sample, shouldnt be hard to get

Ange, they are hard to get. That's why there is an advert here. I've missed the last ship for the year by a number of weeks now and though it was worth a shot asking on here.

Unfortunately, my location isn't exactly urban, more jungle.

If anyone is able to help please speak up, I understand some of you find this advert frustrating but quality hardware stores are few and far between in my next of the woods, ahem, jungle.

ahh ok now i understand!

whats interesting is the pic of your original bolt, the head of it in particular
i havent seen one like that, i wonder why it might have been designed that way

Never seen that type of bolt before.

Cut the nut off as I did,we have plenty of bolt shops in town and none could match it.Thats why I did it that way.
