Yah I'd love to keep this van around, but don't have the room. Need to make
way for a Jetta donor at some point soon......
Yah IIRC, the 122 was first with a shoulder strap, and an alternator. And I
remember now. On the 140's, the brake bleeding was more involved. Something
like 2 bleeders on each front caliper.
Thankfully someone on this list suggested getting the visor clips. They're
now safely stashed away. --- :^) I may even get down to grabbing the wiring
harness though I did a foolish thing by hastily cutting it at the front of
van --- :^( There is lot's to take. I had no idea before I got into it.
So many parts. Even the little junction box in the engine bay looked
attractive. Not sure if I'll need it for my conversion, but I saved that
too. You never know......
Neil.
