Wanted - Fork tubes for XS1, XS1B

[Cafefill]

Wanted- a good set of fork tubes for '71 XS650. Mike's only stocks fork tubes from '72 and up, although the seals appear to be the same size. Would also entertain buying two complete forks, if the chrome is good on the lowers. However- if someone knows if fork tubes from the later 34 mm models will fit ('72-'75), I'm good.
Thanks.
