1976 Sprint, single master cylinder. I have no idea which unions I need to buy, is there a list of the required ones anywhere?

It is quite easy since these are Imperial fittings.
You need 3/8"UNF for 3/16" brake pipe, both male and female.

The quantities vary from car to car but for your car I think it is,
BMC to 4 way union.....2 males
4WU to flexis...(2 pipes) 2 males and 2 females
flexi to caliper ....(2 pipes) 2 males and 2 females
4WU to joiner....1 male and 1 female
joiner to flexi ....2 females
flexi to wheel cylinder...1 male and 1 female
wheel cylinder to wheel cylinder....2 males.

Totals:
10 male and 8 female.
I have listed them so you can double check the quantities. One 25' roll of brake pipe is sufficient.
(You can do away with the joiner and have one long pipe instead of two shorter ones if you wish.)
You can buy these unions from any motor factor.

These links show what you will need, but you will be able to buy these unions at a better prices for sure.

I would also opt for brass fittings over steel and brass bleed vlaves as they don't rust in to the brake calipers.

Malcolm

Thanks both - that's a really big help.

Hi guys, i'm in a similar position, how much do the fittings vary from this to a a 1977 Dolomite 1300.
Thanks

The brake plumbing on yours will be pretty much identical. You just have a smaller servo and no load sensing valve
so your rear pipe is just one and not two.

What year is Dave's Sprint? If it is a later car it might have the tandem brakes. Dalton's has single line brakes and as Jonners has already pointed out, it has no load sensing valve and a smaller servo.
