how many door panel clips do i need?

year one has them but they get you on shipping. my 66 takes 10 on the doors and 2 on the rear panels. 1 bag came with enough for a front and rear panel. $13.20 per bag of 12. i ordered 2 bags for a total of $26.40 PLUS $10.32 shipping.
i did try r/t on the 8th but still havent heard back from them.
