Why won't this manifold fit!!?

[Bluegrain64]

I need to replace my cracked exhaust manifold on my 64' 292 c30.

I've posted before on this subject so try not to flame me! I had some excellent answers regarding OE used manifolds but I'd like to go new if possible.

I have no clue why this says it will NOT fit!

It says it will fit 65-79 but not 64...

Were 63-64 292's different? Previous answers from my other thread say no, all were similar until the intergrated ones came out.

Thanks for any help/insight.

They didn't send you a 235 manifold did they?

1963-87 292's with non-intergrated heads were the exact same darn thing. Outfits like those are full of crap. Summit racing tried to tell me I needed a different bell housing for the tremec to bolt up to my 292. Well....it bolted up no problem to the stock bell housing.

I didn't order it yet cause they keep yapping that it won't fit.

Same response when I called them on this manifold, except they didn't have an alternative.
I'm just going to put this to bed and order the damn thing!

I put much more faith into guys on this forum than I do from Amazon or Summit!
