As Arran mentioned the original are very stiff and the sound quality suffers. Same holds true for the models 20,21,70, and all the versions of the 70 and 90's.

Am thinking that maybe adding some diluted fabric glue may give you a bit more strength and not lose the important flexibility. Would make the screw hole slightly larger so it can aid the centering the vc after assembly. No play in the originals. The tricky part is getting the spider and vc glued together so that they are not on a slight angle same with the spider to cone junction too.
