Repair terminal on the back of 69 hazard switch

[Classic]

Putting my 69 back together and was refitting the dash switches, when pop! One of the terminals fell off, with half the rivet attached.

My question is, has anyone had success repairing/replacing a terminal terminal on one of these switches??

It is a 69 hazard switch, and NLA, and it looks like it was a one or two year only part.

Was thinking, maybe a small screw to attach it to the remains of the rivet in the body of the switch?

It is the L terminal, which appears to supply the left indicators, so another thought is to put a doubler on the R terminal, and run all indicators through that terminal?

Your thoughts, suggestions, and any experience.
