reverse light switch

I disassembled my reverse light switch on my 67 dart. I found that the springs that push the contacts (2) and another that pushes a plastic part (1) were rusted and/or broken. They are very small but there are many suppliers of small springs on the net. I ended up paying the piper and bought a NOS and did not pursue springs any further. To disassemble mine I drilled out the two rivets and planned to reassemble with two bolts and nuts. Be sure to record the orientation of the parts. To get the correct springs, measure the spring wire diameter, number of coils per inch and outside diameter and length of the 3 springs. Good luck.
