The 740XTZ are the newer version of the Wossner kit ...this is my problem , the rings are bigger than mine and cannot be fitted ...What does 'mea40XTZ' relate to?
You'd be best off emailing Wossner Europe in Germany > info@woessner-kolben.de
The quickest way to find out is to order the 740XDS set and see if they fit. The list price is only $33.10 so it's not much of a gamble.
