What is the correct part number? I got the 99004.110 adaptor and it's slightly too large for my intake manifold.

the is a 81 datsun 210 HB with an A15 and 'federal emissions'

Do i need a different manifold or did i get the wrong adaptor?

if your in australia, its redline part number
10-212 for a 32/36 onto a nissan/datsun a series manifold. they ship overseas too, have a look on their site, it should cost $44 plus shipping

99004 100 Redline Adapter
?
odd listings. this is the one I got.

Send it back. All the a-series have the same bolt pattern and bore size (except the A10 which is smaller).

I'll have to see if i can send it back after it was opened.

well the old adaptor will go on ebay, they can't be returned.

B310 & F10 74 ON 99003.821

as it said in the listing DCOE

I'm at a loss, luckily i don't have to pay the $150 for the cannon intake.

is it possible i have an A10 intake? look at the scan of the base gaskets...

A10? I doubt it, it was never sold in US. In any case they are the same gasket ...

It looks like you have the L-series gasket. Take a look at this comparison, third photoWeber A-series versus L-series "kit -provided adapter"

i'm off to buy some metal stock to make an adpator plate. There just doesn't seem to be an adaptor available, the kits may have the right one, but they keep the part # a secret.

I'm gonna get enough stuff to make 2 adaptors so i might have one to sell.

I ordered one a month ago and its still not here! I lost my part number...but will try to find it for you.
