1970 Datsun 1600
Be ready to weld in some decent sheetmetal, as the diamond plate aluminum under the hood likely hides some nasty sins. Otherwise, this engine-swapped Datsun Roadster should be plenty quick, with close to 160hp for under a ton of weight.
The stickers will come off easily, thankfully. We’d probably spend some time fitting more period appropriate seats and an original dash as well, but this could be a good starting point.
It’s on eBay in Southern California with reserve not yet met.
