Help! - Rear brake cylinder bolt size needed!

OK, so my brake saga continues down the slippery slope of doom

Having taken one of the drums off, to take the shoes off get the adjuster out to clean and service it, one of the solenoid rubber just falls off pretty much resulting in brake fluid everywhere. No problem, I have new ones I will fit those. OH NO YOU DON'T says Mr Jimny!

The brake line union nut was rusted on and rounded off with a sniff of the spanner, so I cut the line, fully prepared to rebuild the line. No problem, all I need to do is unbolt the cylinder . NO NO NO the J says again! These have rusted up and rounded off in no time.

Now I need to drill the heads off and find replacement bolts

So, I need to know the size and thread pitch of the rear bolts that hold the brake cylinders onto the back plate. Does anybody know? I will email the manufacturer anyway to ask, but just in case anybody here knows...

I want to cry very hard......

Normal 10mm bolt head size will fit from any one that sells bolts take the wheel cylinder with you and then you will no as for the pipe union that may be main dealer only if i remenber smoogy had truble finding new ones

The brake pipe unions etc. are pretty standard, let me know if you have problems as I have a couple of boxes of the male and female ones in the garage.

The unions are not the problem, they are M10 bolts with a 1mm thread pitch. Halfords do them, and I also have some brass ones which I will fit to the cylinders as they wont rust up.

Its the bolts that hold the brake cylinder to the rear back plate they I need replacements for. They are smaller than 10mm across (thread diameter), probably about 5mm.
