I’m searching for any known company that makes such a add-on kit. I can’t find it even though I’ve been told their out there, I haven’t had much luck finding it. And the C-130 spectre models are always out of stock.
Testors/Italeri made a 1/48 C-130E or H some years back IIRC. Try looking for that kit… I presume you are looking for a 1/48 kit?
Yep, it’s hard to understand what you are looking for. A Spectre is an AC-130, which can be an E or H variant, or even an A. Is it the gunship conversion parts you are looking for? In 1/72 or 1/48? Italeri made both sizes in kit form and made a dedicated AC-130A kit as well in 1/48 that I know of.
There is even the AC-130U, which I think Italeri has done in 1/48
