Do a search here, it's not as simple as plugging in a speedo fitting...... Another, maybe simpler solution http://www.abbott-tach.com/cablex.htm
There was a guy selling the conversion service on Ebay.You sent him your parts,and he did the machine work.May still advertise the service.
No it's not simple. The electric housing's hole is at the wrong angle and location. KatoKings welds in a new boss and machines the proper hole for the mechanical sender. He also sells the drive parts needed to complete the conversion.
a lot simpler option if you're interested..I bought a gps speedo sender from speedway for about $140-150. simple 3-wire hookup & works great...only drawback it takes 6 blocks or so to acquire a signal after being in garage.
You could fit one of these , most likely better than the speedway one as this is made in the USA , then others followed copying. https://www.speedoservice.com/classic-speed--.html
