I can't change the title as I was rong it's not a 1972 vette it's a 1970 sorry for the mix up every one. Well any way how I made this Revell 1969 vette coupe body into a 1970 vette body. ha Ha here's how I did it.
First I cut out the revell 69 side vents. I had started making a laytex mold of the AMT '70 vettes side vents.
I also cut out the rear exhaust pipe space. On the '69 those sections are half round and on the 70 models there square.
