I have a pair of new in box SU carbs built in the Datsun original specifications. SU supplied the original carbs for the Fairlady project, as production ramped up, SU sold a license to Hitachi to build the carbs closer to the Nissan factory in Japan. These are runs of the original specs, with the soft material upgraded to tolerate ethanol content. These are excellent restoration pieces, nice and shiny. $975 plus shipping.

...and they have a warranty.

They were designed and built specifically for the the 240, 260, and 280 Z cars. The HIF design was chosen to fight the vapor lock issue. The carbs use a dual pass through fuel feed to insure that the floats are loaded equally when subjected to cornering loads. These carbs utilize a temperature compensating device to make them more friendly in hot and cold weather. The use the same fuel pressure as the original Hitachi versions. They bolt to the stock manifolds and use the much of the stock linkage. Adapters are available to fit stock air cleaners. Screen fitted velocity stacks are also available. Work has continued on the dyno, and the latest versions are configured more toward performance (although the 2018 version meets or exceeds the orginal Hitachi roundtop performance in our tests). The bits reacquired for this are easily retrofitted if desired. All of the modern needles will work if your custom cam and headers require it.

At least we know the Truck Lites fit. Thanks, that is the kind of info I needed. t.o.

It is indeed an alternator with an external regulator

Good point. I do not see mention of this problem, so far, in any of the product reviews, so I hope that this, and the polarity issue, have been addressed. You would think that for $500 a set, they would have dealt with it. For me anyway, one of the primary goals is to take the strain off of the electrical system, the other being better light of course. My '72 has an old school generator with a voltage regulator. Usually the over-voltage condition occurs with alternators, I am not sure if the generator would have the same problem, or maybe a different problem. Sure would be nice to find somebody that has used them for 40,000 miles.......

Interesting point. All of the ads from Phillips and GE state that they are 'direct replacements' . They do have an aluminum back, and they are heavier than traditional seal beams at 3.4 lbs. each. No mention is made of polarity, but yes, that needs to be considered

$250 X 2 is fine if the product is good. I just don't know anyone that has first hand experience with these headlights, especially with the odd mounting in a 240.

There are a number of 7" LED headlights available from GE and others. They are expensive, around $250 each. With other LED replacements around the house and shop, the LEDs use much less power, operate much cooler, and produce comparable light. They would seem to be perfect for improving the lighting on my '72. Has anyone used the LED sealed beams?
