Isn't the Arrow the same thing as the Dodge D50?
Wasn't the Rampage basically the front half of a Plymouth TC3 or Dodge 024 with a small pickup type bed on back? Can't say for sure about the Rampages, but the first generation Dodge Omnis and Plymouth Horizons (1979?) both 2 door hatchbacks and 4 door "boxes", had a 1.7 Volkswagen engine. Actually it was the 1.7 VW diesel block but with a different cylinder head. VWs had 1.6L gas and 1.7L diesel engines whereas the D
odge and Plymouths had the 1.7 gas only.
It wasn't until the next generation of front wheel drive Chrysler cars that they had the Chrysler built 2.2. Until recently, my boy had an '84 Chrysler Laser. Not sure, but I think 83? was the first year for the 2.2 and I believe '85 or '86 was the first year for the turbocharged version.
