Black Ignition Coil

So I may be the last person here to learn recently that Bosch ignition coils are backordered since forever with no delivery dates yet in sight. I'm  in need of a new or near new black coil (Bosch 00010) for my '76.

What are people doing currently with respect to replacements/substitutes?

Thanks.

New Bosch coils do not have a great reputation. 
 

A lot of Porsche guys run 30-40 year old coils and carry a spare equally old coil. A good “old” Bosch coil is very reliable. 
 

MSD high vibration blaster coils work well if they fit your application.

I finally "caved-in" and replaced the stock points and coil on my '76 with a PerTronix ignition module and coil.

PerTronix Ignitor II (p/n: 91847V) with a 0.6-ohm Flame-Thrower II Coil (p/n: 45011).

You bypass (or remove) the resistor wire.

I try to keep my car tuned as best I can with the stock components (original owner), but after making the change to the ignition, I noticed a big improvement in starting, idling and cruising. Better fuel mileage too!

I'll never go back!!!

Very helpful responses from everyone, thanks.

My take away is rather than waiting for Bosch coils to be available once again, perhaps I should seek out an aftermarket coil suitable for my application, including possibly a PerTronix unit, since I am already running a PerTronix Igniter II as John suggests, along with a black Bosch coil that looks like it might be original to the car. 

Thanks all for your replies.

Matt,

The original black Bosch coil is 1.9 ohms plus the resistor wire (0.9 ohms) gives a total coil resistance of 2.8 ohms.

If you keep the Bosch coil, be sure to bypass the resistor wire. 

PerTronix recommends a 0.6 ohm coil for the Ignitor II with NO resistor.

    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
