I'm looking for a starter jumper clip #2984503. It is a small steel U shape clip that plugs into the 2 purple wires under the dash to make a complete circut to start the car on 4 speed cars I have made a jumper wire but would like to have the proper one in the car, All 66-68 cars came with it.

 

I just might have that part. I'll take a look tomorrow & get back to you.
