I'm not sure what you need to mark this solved. Here is more information from the web:
11/08/2011 anonymous source on justacargeek.com blog posts detailed info:
these pickups were made in the former check republic then shipped to Halifax Nova Scotia Canada to be finished ,IE.Optional Equipment.The following things could be added - 15 inch BWA mag wheels and Wrangler tires,Running boards,Sun roof,Fender skirts,Heavy duty spray on truck bed liner.Other wise the truck was sold with the standard steel 16 inch rims with heavy duty tractor tread voltyre brand tires on and none of the above optionals.As for the tail lights they are not Chev products at all but look very similar. As for the cabriolets they came in the same standard tire wheel configuration from Czechoslovakia.The options being running boards,BWA mags,Wrangler tires.Most of the pickups and cabriolets shipped to other countries did not have any of the options applied in Canada.The tires put on them were the Finland built Hakapelleta Nokians.(The second tire standard to fit the 16 inch steel rims).
The web site madeinrussia.cz has detailed info about the history of Lada. They indicate:
In 80’s, Lada Niva 2121 was mass converted to pickup in Hradec Kralove, Czech Republic, and then exported to Canada.
The madeinrussia info seems to confirm what anonymous posted on justacargeek.com
The Canadian work on the Lada's was performed at a location called "Halifax Autoport", which might have been at an airport. The Canadian company involved was either called "Lada Cars", or "Peter Dennis Motor Corp."
Madeinrussia also indicates the Czech Republic produced a variation on the Niva called the Praktik, which is a longer Niva, with more cargo space behind the rear wheels.
