Places to start. Just used the search feature and the words "hood bow". Not allot of subjects that have not been discussed once or twice since the crash of the original forum

When you park it or store it after driving, leave the hood open (unlatched).  The sand bag idea in the sun during the summer will help.

Having owned a 69 I can tell you that it lends a sense of originality to the car. For real .

Keep in mind that if after taking off the springs that hood lays flat then the sand bag trick will most likely not make a difference. The bow is sometimes caused by the flex of the otherwise flat hood because of the tension exerted on it by the springs. If it goes flat when no springs attached most likely the only fix is going inside the inner structure and reinforcing for strength so that it will not flex when spring tension is applied. 69/70 are suppose to use regular Mustang springs . Sometimes the lighter tension springs like used on later 67 Shelby may help but the lighter tension springs may not be able to hold the hood open fully or only hold it open if no breeze is present. I learned to take the springs loose quickly if I had my hood down like when driving by unhooking the front of the spring and letting it hang while the hood was closed .I used a hook tool very much like the space save hold down that I kept handy for attaching or un attaching the springs when needed. If your hood stays flexed when springs are un attached then disregard and try the sand bags fix.

I have the original hood on mine and it has almost no bow in it at all, I wonder if repops are thinner fiberglass?

If the top skin is bowed like the photo, then the subframe is bowed, be it metal or fiberglass. Only correction I know of or have done is to make a series of cuts across the subframe about 1/2 inch apart for about 18-20 inches. Remove the bow slowly with the hood on the floor and some blocks of wood underneath at the corners, then weights on the topside. Once the profile is achieved, it has to be flipped and the subframe welded, or glassed to retain the profile. Good luck , it can be done

They are all fiberglass so as stated above you can reinforce it, can you post a photo of the underside of your hood?


The underside should look like the image of the frame shown here:
