I just purchased these thinking they were 33mm because of the stamping on them, but when I measured them they came up saying 35mm...what do I have???

Does the bore taper inwards towards the slide (down to 33)

On the engine side, the aluminum piece is removable.  These come in different lengths and diameters and some of them have an internal taper. 

Remove the aluminum tube and measure the inside of the bore where it threads in.

Sounds like you got it sorted, but with the new format I wanted to see what adding a doc (pdf) would work/look like. Not sure if you have this or not, but here you go. 

OK that did not work when I attempted to insert the pdf lets see if I do not insert it?

It does not appear to have worked either?

Those spigots unscrew and you can swap them out for different ones, I've made some custom ones to adapt FCRs to a KZ750. Ideally the bore is tapering towards the engine, not the other way around.

This has worked just fine GD4, if you click on the attachment you can then download it (windows10 on "Edge") the later versions seem sensitive to the system you are using. After the last update my old I-pad couldn't access the filebase and now I can't reply to posts with it !!!!
