Description

Greeting all. Great news, after a year and a half of design and testing I have finally finished my latest project. I now have for sale replacement distributor magnets for all matchbox Datsun distributors. This is the magnet that most people find broken when they do a distributor repair. The original magnets become brittle and stick to the stator and usually break in multiple pieces when you pull the stator off. The magnet has become NLA (no longer available) from Nissan. I purchased about 30 of them a couple of years ago and sold them and tried to order more and they were all gone.
I thought that finding the material to make a reproduction magnet would be pretty EZ.....not! The issue is that most flexible magnet material is not magnetized correctly and has very poor magnetism retention and the material is not suitable for hi temperatures. The material will loose its magnetism and the material will degrade when exposed to temperatures over 150°. After contacting all of the big magnet experts I was running out of hope and that is when Captain Obvious contacted me and we talked about what I was attempting to accomplish and he suggested a place I had not contacted. After contacting this company, I was able to purchase a material that is the same thickness and has a temperature rating of 250° and has the correct polarity needed to generate the induced voltage to trigger the ICM. The sample that was sent to me was cut out and tested in all 3 of my Z cars and I then sent it to Captain Obvious for some in depth bench testing for signal strength and quality.
The results of the bench testing were great. This replacement material actually generates a higher signal strength at both idle and hi RPM ranges.
Peak voltage at idle for an OEM magnet was 1.28v. Peak voltage with my reproduction is 1.68v, that is a 25% increase in induced voltage signal strength going to the ICM to trigger the coil.
Peak voltages at 2500 rpm for an OEM magnet was 2.96v. Peak voltage with my reproduction magnet is 4.00v. That is also a 25% increase in signal strength.
With the higher signal strength, extremely hi temperature rating and an exact copy of the design my reproduction magnet is a great option when rebuilding your distributor. Couple this with my improved breaker plate bearing retainer and you will have many years of reliability from your distributor.
Here is a couple of pictures of an NOS Nissan magnet next to my reproduction magnet. I challenge you to tell me which is which. I had to mark them to tell the difference.

A huge thank you to Captain Obvious!

The parts I sell are in Mandan North Dakota. I can be contacted either thru a private message or you can email me at chaug@bis.midco.net or text me at seven zero one -471- fifteen thirtyfour. I sell the magnet for 35.00 and the breaker plate bearing retainer kit for 30.00. If you want both I can cut you a deal for $60.00. Shipping to the lower 48 USA is included in the prices.
I do ship international. I have sent Breaker Plate Repair Kits to Europe, New Zealand and Australia. Shipping for international has been in the $18.00 - 20.00 range

I think it's even 34% more!

What is a matchbox distributor?  Is it like a 280zx distributor? without the contacts like a 240z original has?  

I never took apart a 280zx distributor.. Is that magnet part inside?

Mart.

The "Matchbox Distributor refers to the Datsun distributor that has the ICM (Ignition Control Module) mounted on the side of the distributor. From 1974 to 1978 datsun used a remote mounted ICM, usually behind the glove box. In 1979 the distributors for all Datsun cars and trucks (4 cylinder and 6 cylinder engines) were changed to the "Matchbox" style. This is the magnet that was used for generating the induced voltage to trigger the ICM.
