The year in brief

The 1970 had a conventional bumper under the grille in place of 1969's wraparound one, and triple vertical taillamps.1one source

The 454 replaced the 427 at the top, at 345 and 390 hp, and a 350 V8 became the standard engine on most models.12

Only 9,562 convertibles were built, and the Impala Super Sport was dropped, by Wikipedia's account.1one source

Wikipedia counts 612,800 Impalas without the wagons, 6,500 with the six, and says a 65-day strike in the fall of 1970 hit the start of 1971 production.1one source
