020 Flange Info

Info pulled from: http://www.brokevw.com/

There are three different types of 020 output flanges: 90mm old, 90mm new, and 100mm.

• 90mm old
  • Used before 1983
  • No green sleeves
  • Thicker seals
• 90mm new
  • Used after April 1983
  • Green sleeve in one side for new housings
  • Green sleeve in both sides for old housings
  • Thinner seals
• 100mm
  • Switched sometime during MK2 era (1986+), but some MK2 still use 90mm

100mm flanges are slightly taller, and as such 100m axle shafts are slightly shorter to compensate
