People wrap entire cars these days so I would think a compound curve could be dealt with.
Wraps are different from stencils or decals. Been in the business for decades and still hand letter and pinstripe. With the Olds AIM I provided, P.G. is still in the process of dealing with the compound curves and layout with the incorrect 442 stencils. They will be refunding my money.
One option is to lay it out by hand. If a tape width is not available off the shelf, just have your local sign shop cut it in Gerbermask, which is what graphics companies use. Some use inferior mask which results in bleedthrough. Or try Finesse Striping. Any knowledgeable restoration shop will have all this info. If one provides a sign shop with dimensions, a stencil or decal can easily be cut.
