I've never measured them.
Neither have I...until now. I have a gennie '71-'73 fender in original Yukon ('Yukky' as my ex called it) Yellow. I dragged it and a square and tape out and made some quick measurements. I'd like to photograph how I measured and start a new thread on the subject so others with OEM '67 fenders can post their findings based on the same measuring process.
This could be a real benefit for people who can better justify carving an inexpensive later fender than spending bigger bucks for a true '67 fender.
I have a set of OE US '67 fenders I'd be glad to measure. They don't have buckets or lights in them. They have horn grille holes in them but the signals have been filled. They've been in my possession since '78 and were original paint until about a year and a half ago.
