It’s 1981 Plymouth TC3/Dodge Omni 024, those names where from 1979-1982. Later renamed the Plymouth Horizon/Dodge Charger for 1983.
Wait, if you know about these Chrysler never sold a drop top. A company based from Toronto called Pony Convertibles did the conversion. They offered conversions for Mustang IIs, EXP’s, 024s, & TC3's.
Pony Convertibles only build 28 drop top TC3's, so it one of the most rare L-Bodies.
I’m not great at ID’ing engines. It could either be 1.7L VW motor or the Chrysler 2.2, I don’t know. If it’s the VW it had 70hp, & the Chrysler motor had 84hp.
