Speed sensor

Just starting to upgrade my Howell biased system with distributor control.
What speed sensor are you guys using. I will also be using a Delco cruise
control from an early 1990 GM truck. If I need to use GM truck parts, I
will.
Thanks
Mike

No trees were killed in the sending of this message and few long dead dinosaurs were involved. A large number of electrons were terribly inconvenienced.

Maybe this? Fits in the 425 trans.

I got my speed sensor from Howell.
I just looked and I don't see it listed separately, but it is shown in
the photos of some of their kits. I suspect if you called them they
would sell it separately.
It goes in line with the speedometer cable so the mechanical speedo
continues to work.
One issue I had with the speedo sensor was I suspect the switch (reed
switch) in the sensor developed a nasty switch bounce. This caused the
speedo on the EBL WUDisplay to bounce all over. That wasn't the
problem... the engine would cut out. The noisy pulses would cause the
EBL to think the vehicle had hit the Overspeed setting and kill the
engine. Randy VanWinkle alerted me to a filter parameter that cleans up
the pulses, and all is good again.

Here is several photos of replacing the reed switch in my Howell speed
sensor.
