here's one i hadnt seen before

Petty Dart. Good to know they reissued it. Will have to pick one or two up for the 70 Dart parts and graft them onto a 68 or 69 kit. Think that is only one of two ways to build a 70 Dart unfortunately.

mother is to get a resin aftermarket body and graft it onto a 68 or 69 kit.

for those complaining about kit quality you should try one. . They suck. Or a vacuformed kit. They are super fiddily. There there are the short run low injection molded kits. Don’t even know how I got some of them together.
I'd just try and modify the rear wheel openings of the LA Dart,detail it's body, use the trunk lid from the Petty dart, and only use the interior and chassis of the revell dart. Revell bodies suck.
