I guess your answer is that there is nothing that has the correct narrow track width and that had a V8 from the factory?

So to use a new frame involves a fair amount of work to make it look right.

And using an old frame and swapping a new independent front involves lots of work too.

Using the old frame with only a rear axle swap and a front disk swap and a v8 mounting kit could be the least amount of work.

Any way you look at it it involves work. Just decide what you want and do it.
