The Dynatec coils do not fit with the original coil bracket. The black plastic cover and the complete mounting bracket was removed. I replaced the wires because, they were original.
To properly attach them to the frame in the same (correct) position, I used a metal strap ( if you ever installed a car stereo in the 70's, you know what this is, I got it at Advance Auto in the muffler section). Quite easy and secure, and when the tank is replaced, nothing is visible. 7 or 8mm wires can be used w/ the dynatek coils, I bought an inexpensive set for a V8 also at Advance Auto, I just cut them to length. The wires came with spark plug connectors, but I reused the original spark plug caps/connectors and fittings to keep an original look. The wires came with everything I needed at a cost of about $25.00. (if I went with OEM coils, I'd use new wires anyway, due to the age.
Also, the secondary connections on the dynatec coils are screw mounted, and the original ones are the usual flat push in connectors, so I just used some 14 guage primary wire to make the proper fittings, keeping the original connectors intact.
I'm not really a very handy guy, and I was able to do it all in one day, so it just takes a little patience. The original Honda coils would remove and replace in about 1 hour, but for me it was fun and worth saving about $100.00. Usually, I like OEM, but again, the savings.....
Some say the Dyna coils are superior to the stock, all I can say is they were manufactured in 2013, and the coils I replaced were made over 30 years ago..... and now the Ascot runs much better. I know its from the coils, because I already know I had clean carbs, a good battery, and everything else is in order.
Hope this helps.. .
