One of the members in the past did take a rub off and had someone cut a wrap for their hood. Do not remember who it was.
I also have two other original hoods in storage that I can pull and also check position and size.
I have no issue with doing the rub off for Hemikiller to work with to produce a file.
I also understand that the current side stripes for the 73 are also incorrect. I did a rub of them in the past also.
I was amazing in the past when the current suppliers were approached about correcting the stencils they were not interested because people were buying what they had. They do not care if right or wrong just make money.
I would think an ad on Ebay would generate some income for the forum selling either a stencil or wrap.
A stencil would only need to be the front end and with proper measurements from the edge of the hood in the rear the remainder is one long straight line so no need for stencil just mask it off.
Another challenge would be to come up with a paint formula that looks original.
The only room for error is how the pattern lays on the hood when I do rub or when user applies to the hood. It is not flat so the paper or velum tents over the high places.
When I did the last one I took the paper to the front of the hood and over each side and marked it plainly so it could be aligned on the hood being done.
I do not remember what the body color strip width was it should be something standard in width. If not years ago when you could not just go by tape about any size we use to go to butcher shop and they can cut masking tape with meat slicer to any width.
Here are some pics of what I did last time just used Craft paper but a velum would be more stable. This was done before I had cleaned the car up. You can see how the paper has to tent over the contours of the hood.
The same thing should be done with an original Sprint hood to get the correct size and location for them.
