G27 spoiler, rare part??

[GinG15]

found a front spoiler from a ginetta g27 in my garage: (it looks like the one from the below picture)






2 questions now:

would this roughly fit to a g20 bonnet?
is it a rare part and how much would it be worth?

thats interesting...i trial fitted it today to a G20..width, radius is ok.


so all ginetta cars since the 70ies seem to be based in certain areas on the same basic-sizes???

but my original question is still open:

is it a rare part? and how much is it worth?

and anotehr question came up now:

does a g27 bonnet fit to a g20?
