window mechanism

Hi, need to remove side panel and check out our 73 beetles side glass at the weekend, as was rolling down the window a few days ago when it suddenly dropped out of sight and wont wind back up! Any advice/tips please or point me in the direction of any info (couldn't see much in Tech Archive)...

after some bits for my 66 bug before i put a order in for them...condition not important as long as they work single curcuit master cylinder 12v wiper motor (67-70bug) accelerator cable 12v choke element large felt guide (for door window) window lifters (double lifter) cheers:)

got a prob with the winder mechanism making a grinding noise and not moving. the window was stuck in a mid position. iv taken the door card off un-done aload of bolts. but how the hell do i get the old mechanism and cable out? it dosnt seem possible...
