Orig Green Big Muff Switch wiring Question

I have an old Army Green big muff pedal with a broken switch.

The Old BMP's Have these strange dual momentry swiches that get held down by a small clip and spring mechanisim with each alternate push.
Mine has a broken spring and will only stay on as long as you hold the switch down.

They operate essentially like a DPDT stomp switch and I want to replace it with one, but I have a problem:

There are and extra two wires that conect to strips of metal on the sides of the switch. These strips are insulated from the main body and indicate another swiching pole is being used, but for what?

Probably the led but I don't think these pedals are true bypass anyway?

I read some thing about the old Big Muff's having a power cut, on/off, mechanism built in to the switch(http://www.diystompboxes.com/sboxforum/viewtopic.php?t=14503&highlight=green+muff+switch)
so this maybe what I'm seeing.

I just really want to know how to wire this up to a normal DPDT switch.

I'm not overly phased about True Bypass or the power cut feature.

Can Anyone help?

If you can find your input and output wires that come off the board, wiring a DPDT or 3PDT, should be fairly followable using he GEO Bypass article.
 Disconnect Power Supply of battery, Use the DMM and hold the old switch in the non bypassed position, follow the wire from the output jack through the switch or not, [you may have to creat anew 'break' for output 'side' of new switching system, ... see if you can take it from here ... let me know !!!
 ANy way take many readings and note whappens with the old switch in both positions...if all else fails, audio probing  the live circuit will probably let you find output.
