Wanted Yamaha OW 26 Parts

[firko]

A friend is about to start restoring the OW26 400 Yamaha ridden by Per Klitland to a close second in the 1975 Mr Motocross series and for the first half of 1976. It then went to Mike Landman. He has most of the bits to put it together except for the following.
*The original magnesium crankcases (He has standard MX400B cases with the original billet crank and hand made trans)
*billet shock and resevoir
*Magnesium rear hub.
Although the bike looks a tad ragged in the photos, it's mostly all there. The intention is to have the bike finished for Per to ride it at CD7 so if anyone has any leads to the missing parts the owner would be most appreciative. PM me if you know of anything or even have the smallest hunch. One tip recently uncovered the mag bottom triple clamp in Rod Tingates MX400B so you never know.
