No they were the correct length just don't have the right piston pin diameter. Thought I would put the feelers out to see how available the A12A Rods were.

Was going to go forged but have since decided to keep it simple and keep costs down for now.

as above bore your a12 rods they have more meat than most other makes rods
been done heaps of time with no failures of any kind.

What happened to the 300 aud arp bolts and rods you said are too cheap to
worry about stock rods? only 133mm ones?

Just machine your existing A12 rods out, it is only a minor modification.

In Japan, they usually call the A12A just an "A12". Though they are common, they are not often recognized. The rods have casting ID "H85". They are sometimes called "A13 TS" rods.

See David Hammond Hear in Brisbane Qld He is on FB Down,under,Datsuns
as well as hear I think he is Whalebone on hear...

Don't the A12A Rods hace more meat around the small end to compensate?

Quote:
Bore the small ends of the normal A12 rods to 19.7mm and call them A12A rods.

Tried Bprojects already. No good.

No idea what to search on yahoo Japan

Try Yahoo Auctions Japan

or Bprojects Australia

I'm in Australia though? I don't believe there were any A12A's here?

I've tried searching around on the net but can't find anything.

Any ideas on how I might be able to get my hands on some?

Not rare at all. All B310 Sunny in Japan had them except for VB310 engine.
