Difference between pre 63 and post 63 window rivets and rollers

[Paul Y]

Morning,

As with all things I have carefully squirrelled away a set of window regulator rivets and rollers in a safe place for later use.

It is now later and the place was so safe I cant find them....

Being in the UK means a week or two's wait for things to be shipped but a local supplier has the pre 63 rivets and rollers in stock.

Is there a major difference between the pre and post 63? In other words will they fit and, more importantly, work.

Would appreciate your experience on this one.

P.
