Heater valve clamping bolt - Porsche part


Recommended Posts

My '75 02 was missing the proper heater valve when I bought it, and I found a used one that I rebuilt. The clamping bolt (shouldered bolt w/ the hole for the cable) was missing, and I was using a standard bolt with a hole drilled in it and some washers / nuts since they were NLA from BMW. The bolt did not articulate properly, causing binding, and I found a post here from a few years back referring to a Porsche part that "looked similar." I took a chance and ordered a clamping bolt for a '65-'86 911 (90121168300) since it was only ~$6. Installed it today, and it fits perfectly! They are available from a bunch of different vendors if anyone else is in the same boat I was.

Given that both auto manufacturers bought

a lot of their components from domestic third parties, this

makes good sense.  Roundie taillight lenses are found on

VW's, as well.


My personal favourite of these is something I learned entirely by

accident long ago:

The Datsun Roadster and Volvo 122 have the same rear parking brake actuators.

The Volvo uses a British part outright, and 

Datsun manufactured it under license from the British.

They look different- they measure and function exactly the same.



no- one escapes the Briddish empyre.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
