Proper Body Panel Gap
I am putting my 72 back together and I am wondering what the proper body panel gaps should be. I checked some new cars and trucks and they vary from .12 to .25. I was thinking .18 or .20, but I am not sure how much build up I will get from the paint and primer and what will look best when it is done. Any opinions?

John, you need to get a copy of the factory Assembly Instruction Manual (AIM) for your year. All the supply places have them and they are very reasonably priced. All the panel specs. are in there, as well as other invaluable info on part installation, etc.

On average, they should be 1/8" to 3/16". But finding one from the factory with those close tollarances throughout the entire car...is like finding the Holy Grail. 
GET THE AIM for specs...some type of body gap feeler gages....and go for it!!!
I used rubber setting blocks in the correct thickness from the glass/window industry to install my doors & hood. Taped them to body panels while adjusting the doors/hood etc to set the gap & protect the paint.
Good Luck

Have the assembly manual, but for some reason I just never thought to check there for the gaps. Does anyone know if those gaps are figured before or after paint? also how much thickness will paint add?

When I built my 73 I used the AIM for all the gaps. It will give you a range, ie. 1/8-3/16. I used the max limit. If you use the minimum limit, the way these frames flex you will get paint chips at the door peaks and other places. I have put 30,000 miles on mine and I drive it hard. I have no chips caused by frame and body flex.
