stay away from mulkis they are crap and the rebuild kits and manifolds are almost twice the price of webbers or delhotos, i got given a set but it would have cost me more to rebuild and set up than to buy a set of webbers that bolted straight on, you can normally pick them up for around $500 i brought my webbers for 700 came with 5k manifold linkages, they had just been rebuild and came with a spare rebuild kit for each one
