I have fitted the new seals on my '97. It is largely as as everyone has said; the existing holes need to be about 1mm larger in diameter as well as the holes nearest the front and rear edges of the door also needing to be relocated by about 1cm or so. Obviously new holes are required on the front and rear edges of each door as previously stated.

I'm O/S at the moment, but if you can wait a week I'll post up photos... but why do you need photos? Just get the seal, put it up to the door, mark where required, then drill.

FWIW, fitting these seals is a great improvement for the amount of effort it takes. Particularly if you have the horrid body mounted seal like I did. No more chilly right elbow!
