Got a cheap round eye 210 coupe for the 5 speed. Was going to swap a 4 speed into it and put it back on cl. ... but ive ben tinkering with it instead... lol whatever.

Wich is weird since its way bigger than an a12 can port to.... but yeah its the bigger of the 2 a12 manis that are discribed in the tech wiki.
Almost got the 4 bolt mani to use roadster carbs, but a fellow datsuner gave me this one so ill use it. Cleaning up the casting and polishing it now.

SU manifolds are standard size. You probably have a factory A12 twin-carb Hitachi manifold, they have the largest ports.

Kinda see where I marked the su manifold to the port.

Did get a h72 today. Should work ok for me.
This.porticular one is drilled out for bothe manifold patterns. Should probably check the oil passeges I guess. See if its modded for a12.

Ok thanks, im mostly keeping an eye open for a junk yard 63a. Ive allways had good luck with those.

It is a 60-series dogleg 5-speed, from a 1979 B310.

That could be a good deal for a 5 speed, wich model?
Thanks for the tip on the needles. I will look into that.

I have a 5-speed for $350.

The factory twin Hitachi carburetors (SU-type) use the same needle and seat as the the stock downdraft Hitachi.
