Is Isomat, Z-Spar and Z.Diffusion the same mast?

[suiramor]

I understand both Isomat and Z-Spar masts have an integral spinnaker car track. RigRite catalog sells spinnaker cars for Isomat but lists those for Z-Spar as no longer in production. My Beneteau 461 (1999) has a mast labelled Z.Diffusion, also with an integral track, which appears to be same size. Are these in fact all the same masts just labelled differently? does anyone know whether I could use the Isomat car for my mast?

Isomat turned/was sold to Sparcraft
Z-Spars: different integral tracks, different cars
IIRC from my base manager days: no way one fits the other
alas

not much to go on...
& from a French forum the reply by Z-Spars:
""Bonjour,

Nous n'avons plus ce chariot de tangon.
