Nice one Ray ! And you're correct , the AMT chassis is almost perfect for the Kyosho body .
There's always this 1/24 Snap Kit , not very good as kits go but the body looks good and it fits the Monogram chassis ! It has the sloped roofline like CSX2287 .
Here's the Lindberg and Kyosho side by side , the Kyosho is a better detailed body . It looks wider in the photo but it's just the camera angle .
