I am rebuilding a 1979 series 3, The hub caps and half shafts on the front axle are not the same as in the manuals. The cap is flat with a centre pin or guide which fits into the end of the half shaft. There is a rubber O ring seal on the inside. Both seals and one cap will have to be replaced. I need help with what these are called and part numbers if possible. There looks like millitary camoflage paint on the caps. Thanks

sounds like you have light weight axle all parts except end cap and oute part of half shaft are the same as std series

Thanks, I know now where to look.
