In 1977
Zastava redesigned the
Zastava 430, using the basis of the Fiat 900T. The biggest mechanical update was the use of a IPM 30 MGV carburetor, bumping up the power of the 767cc engine from 25hp to 30hp. The name was changed to Zastava 435. Body variants included: 435K (Minivan), 435F (Panel Van), 435FP (Panel Van with windows), 435T (Pickup), 435FM (Police vehicle), 435S (Ambulance). In 1980, the 435 was slightly updated, getting a coolant temperature gauge, and new taillights. That year the 435 gained the engine from the new
Zastava 850, a 847cc unit developing 32hp, and was renamed to Zastava 850A. In 1985, the engine was changed to a 903cc 45hp unit, borrowed from the
Yugo 45. The name was changed to Zastava 900A. A new better equipped model was also presented, called the 900AL (L standing for Luxury). This included: front seat headrests, better quality seats, better sound isolation, and black anti-glare plastic dashboard. Production of all variants ended in 1990. ==Models==
