I have some various speedwarning parts and a back tach tin for sale.
1. Speedwarning back tin. I removed the brass lug and painted it inside and out. I was going to use this as a template to drill the two holes on my tach tin listed below, and reattach the lug to it. Tin and lug are $45 Shipped.
2. Tach back tin. Painted inside and out. $45 Shipped.
3. Four speedwarning cable nuts. $10 Shipped each.
4. OEM Speedwarning buzzer. From an early Buick. Only difference is that it does not have a mounting bracket like the truck one. It plugs right into a truck harness. It is tested and works perfectly. $75 Shipped.
5. Speedwarning input gears. The blue plastic one is OEM. The brass one is identical and was used in later model speedwarnings...this one will never break

$20 Shipped each.
6. OEM Cruise control/turn signal lever. Similar to the chrome one used in our trucks...but NOT factory correct. $25 Shipped.
7. New Chrome gauge bezel. $35 Shipped.
