tired of my twin 40 DCOE's falling out of tune everytime I drive my Datsun. So I am looking to buy a manifold + down draft weber.

There are a few stores in Australia where I can buy them new, but they want like 1K for the kit (weber, manifold and adapter if needed)

Just thought I would ask if anyone has anything to sell so I can save some $.

I also have two spare 40 webers, dismantled at the moment. Would be happy to trade them.

My existing A15 head is heavily ported with 10:1 compression, so I will likely need to bore out any manifold I acquire so they semi-match.
As far as I know any stock A15 manifold would be OK, with an adapter plate which I can buy.

thanks
