I have an opportunity to purchase a six speed tranny from a 2004 911. I wonder if i can fit it to a pan based 1982 IM speedster D. Any ideas?/Suggestions?

Well I can tell you this. NO. The late 911 transmission is so different in many ways
#1 the bell housing will never work with a VW or Porsche air cooled engine.
#2 it uses cables for the shifter
#3 its much larger that your VW transmission, you will not have the room to fit it
#4 It still will not work for what you want it to do with it
But you should definitely still try, posting pics of the entire process here.
I have a 901 five speed in my IM, and apparently it is not a major process to make it fit.
The 912/914 4/5 spd trans (901/902) is one normally used (a 70-72 914 works too but you need Porsche nose cone and other work). It takes cutting of rear engine mount horns and the chassis. There is good article on line - links were posted on here. It's a direct bolt up to the T1 engine. The larger newer 915 trans can be used too -just lots more cutting and clearancing.

I think later transmission got even bigger. I do recall SAMBA article discussing their use. Super info - but made my head hurt.

One you have a line on must be a 95 model year G50/20 Transmission. The SAMBA article seems to like it for a Vanagon. You'd need a really powerful engine to use 6 or 7 spds I'd think.
The G96 is a good transaxle capable of handling 400-800 HP depending on if it came from a turbo car or not. But mounting, the significant extra length, cable shifter, and possible all wheel drive depending on version make it a tough swap. Genereally the older G50 is used in the mid-engined kits (GT40s, GTM, Ultima, etc) for those same reasons. You'll need to spend a significant amount of time, money and thought trying to fit it into your chassis (possibly more than the car itself if you assume your time is worth something). If you can get it cheap, probably better to resell and go a more traditional route.
Geogrim1, the short answer is no, but with enough effort and money almost anything is possible. The one of the problems with the newer 6 speed trannies is its length. Even a G50 puts the engine back too far.
Three 5 speed transmissions that can be fabricated into place are the 901/915 Porsche gearbox, the Gene Berg gearbox, and the Subaru gearbox with the reversed ring and pinion.
I have installed multiple 915 transaxles and we now offer the full conversion for them..... Basically for around 5k you can get a 915 trans into your speedster and never have to buy another trans ever unless you go above 400hp
