Drive shaft oil leak HELP

i have a 1983 mk1 gti and
iv recently noticed iv got oil comming from the joint were the nearside driveshafts goes into the gearbox iv been looking for a new seal but im not sure whats the right thing to get

on crazyquiffs it shows a flange kit and then a input shaft seal which its the right part
i also tried GSF and they said they didnt sell it all i need is the seal that surrounds the drive shaft were it enters the gearbox !!! any idea's

Im also looking for a sunroof if anyone has one going as mine has a hole in it
and window seals for drivers and passengers door
and passengers side window runner???

Flange kit.  Check out 020 Flange to see whas involved.

Try main dealers VW as they sometimes do old parts.

Is there a company that manufactures new Drive Shafts ???

BTW that link is really helpful mate on Broke VW
