I'm Going In... Radio Saga Continued...

I've posted twice before on the problems I have been having with my
Narco radio's:

I've decided that I'm going to pull the radio and the connector tray
and run new coax from the radio to the antenna, after cleaning every
contact point I can find with contact/connector cleaner. I figure the
worst case scenario is that I will have spent $20 - $30 for cable,
which is far less than taking it into an avionics shop for more
troubleshooting! Been there, done that!

I've pulled the radio out several times during troubleshooting, but
never paid attention to what would be entailed in pulling the connector
tray. For those who have done this before, is it going to be blatently
obvious when I get in, what needs to be done? Is it pretty
straight-forward, or am I going to be squeezing my head between the
rudder pedals and scraping my arm and knuckles on all of those hidden
dangers, lurking behind the panel?

Any tips or recommendations on how to pull the connector tray?

My thought on running coax is to do it as if I were pulling electrical
wire... Tape a new coax end, to the old coax end at the tray, and pull
from the antenna end to feed the new coax through. This way, I
shouldn't have to pull any plastic.

Any suggestions or lessons learned will be greatly appreciated!

Thanks and Best Regards,
Todd
