Driveshaft size

Hi

im looking to replace the ‘drive shaft constant velocity boots’ on the front of my 1988 clipper cabriolet, but all suppliers have 90/100mm parts available, is there an easy way to tell which I need without measuring them?

1988 cabriolet should have 100mm CV joints if original.

Quote from broke vw website so it's in inches..

If you take a bit of string and wrap it around the inner CV joint.

A bit over 11" (11.13) and it is a 90mm CV/flange.
Just under 12.5" (12.36) and it is a 100mm CV/flange.
