How do I measure front and rear fender flares?

[74vert]

I need to know how to measure my front and rear fender flares so i can buy fiberglass bumpers. I think i have weld on rear flares or maybe a factory option.

Can i tape two rulers to outside of fenders and use a tape measure to find distance between them and then post here for an answer or does anyone know off hand the distances?

I may buy fiberglass front fenders so that may not be a big deal then

Measure from inner structure of frame to fender lip

I will try that and post and you guys can tell me what they are. They go from a curve to straight down kind of a flat lip.

Front measures about 11-12" rear measures 14-15"
Front tires are 225 rear are 255 roughly 9 and 10 inches and fill up wheel well to outside of fender but I do not know offset or if I am measuring correctly to the body to edge of fender.

Any examples or ideas?
