are the tele finders from other companies compatible with yashicas?

[dragonx]

i keep missing these yashica teles on the auction site.
currently, i have a universal finder by accura that came with my canter beauty RF. also have a lovely petri finder on the way from fellow user, cbass.
will i be able to use either of these with any of the yashicas?
or are there other companies' finders which are compatible?
please share.

If you talk about the aux. finder for the Electro 35, this one gave the view for aprox. 35 mm and 60 mm (or something very close). Then it would be difficult to find a finder for this last focasl distance, but any 35 mm viewfinder would be OK.
The only that´s bad is that using the converters in the Electro 35 is like getting into a bad nightmare.
