I think I have a pair I picked up at my garage. I'll be going there late on to work on my car. Do you just need a pair?. If I can come up with them (I may have given them to my buddy so no promises) you can have em for the price of the ride. Let me know.
I used a drawing like that to make a plywood pattern that is very good when put up to a model a frame. Send me 10 bucks for postage and I will put your name on it and send. Its about 30'' long on 3/4 ply.
Paul, Thanks for drawing. Does the 9 1/2" dimension in your drawing refer to the center of the 1" radius circle? Also, the radius describing the upper arc of the horn is 1' 11 9/16"; add the 2 9/16" horn width and you get 26 1/8", which is almost the same as the 26" radius describing the lower horn arc - do you think they are supposed to be the same? Is it a question of where the 2 9/16" dimension refers? And do you have a reference on the x-axis, such as a rivet hole for the front cross member?
48fordnut do you still have patterns for the frame horns? I can't get the one from this post to open its DWG.
