Good morning from a chillly winters day in South Africa
 
I recently (yesterday) purchased a 69/70 model Datsun 1000 ute. Now in SA, as far as i know, this is not a common model we got, so parts may be a bit difficult to source and importing is not an option with our eceonomy and exchange rate.
 
We have alot of older1200s and the Nissan 1400 ute was sold here until mid to late 2000s as a Nissan 1400 Champ so spares are in abundance for that model.
 
Would some of the spares be interchangeable? Specifically braking system, my 1000s brakes are almost non existent, pedal is almost on the floor and pulls violently to one side on hard braking. Im assuming brake cylinder kits are needed due to age and most likely worn out. Also the handbrake does not work at all, not sure if the cable is broken or if the cyclinders are worn out. 
 
Any info would be appreciated. I have not had much time to research as yet but i thought id ask on here and see.
 
Thanks everyone.

I believe the early datsun 1200 models with drum brakes at all wheels have the same brakes as a datsun 1000.
 
For the rear I believe there are two slave cylinder diameters, one for drums all round and another for use with front disc/rear drum brakes, the difference in slave diameter is to set brake bias for the differing systems.
Either size will work in the diff, so if only one size is avaliable then just run what you can get your hands on if you are looking to buy a relpacment part.
 
For a 1200 with drums all round youll be looking at the earliest models, from the early 70's  and not later versions, so if your parts store doesnt have a listing see if there is an earlier option to select.
 
But as D has suggested,most brake shops should be able to recondition what you have and in my opinion this is the better choice as some aftermarket brake parts are poor quality and seep/leak after short periods.

I figured the early 1200 all drums would be hard to get but you might still get parts
as suggested by BeeTwenty.

The early datsun 1200 coupes had the hubs you need for a front disc brake conversion
and you can use the whole lot as long as you fab some brake caliper brackets and use
the dual master cylinder that belongs to it.

You would be better off with better brakes if you are going for an A15 but if you can just
go for an A13 or A12 as the gearing even with a 5 speed is better for highway speeds
or in general as the b20 is so light that it needs 3.1 diff ratio to reduce engine revs.

The A12/13 rev better as well, smoother and much lighter than A15 block unless you
have a tall A13 block which is rare but comes with smaller bores and 77mm crank.

The A12 bored to 76mm and lightened crank makes a super light bottom end.

I had a worked A12GX motor from an ex speedway racer that was easily 10kg lighter
than a stock A12, which could be lifted so easily vs the stock A12.

The secret is to keep the B20 as light as possible as they are the lightest proper car
with protection from the elements that challenges a Lotus 7 pound for pound.

no problems, wow A15 fitted must take off easily from almost any gear! I had 3.9, A15 and 5speed overdrive but still rpm too high, specially at a 100. My stock A10 59mm 4 speed 4.11 was the only combo that sounded good on the freeway up to 120kmh.

Good morning Tbird.
Glad to join this forum.
I am also from South Africa, Somerset West.
Also bought a 1000 ute B20 and am busy to respray and trying to get it more original, but struggeling to find parts.
Not that I need any, but specially the window rubbers for now.
Do you know where can I find window rubbers that will fit?
I attached a photo of my B20 before. Will send a new photo when it is finished.
