Need some help if anyone can.

Ive got a set of genuine GM skirts to go onto a veccy, there from the facelift model, 96-99.

Ive bought a full set of clips from VX to fit them, new expanding rivets for the under4side and endcaps, new plastic clips to go from studs to skirt, and the stud rivets which hold the clips to the bodywork.

Prob is without fitting diagrams i dont know where to position the rivets to hold the clips in the correct location, and dont want the skirts on wonky.

VX nor the VX bodyshop can supply instructions, nor can autovaux.

Anyone here got a link to the info or old instructions that show stud positioning they can scan in?

Most appreciated, jamie.
