1975 and 1976 saw relatively little in the way of changes for the bus, with only minor changes occurring, the previous stainless steel mirrors had been replaced by painted steel items on all but the Deluxe models. The Type 4 engined bus had a capacity increase from 1800-2000cc, the Type was also now available in pick-up form.
In the last three years of production, the Bay saw little in the way of updates, VW were busy working on the T25 (the Bay’s successor) externally the engine lid hinges were changed to a more simple design, internally, mechanically and electrically the bus was largely unchanged.
M-Numbers are VW’s way of distinguishing optional equipment, for instance M020 was a speedometer in MPH, and M032 was a lockable fuel cap. M524 was a variable option, but basically covered all the options that would have been standard fit on US and Canadian spec vans.
It included, padded dashboards, side markers, all-red taillights, twin filament bulbs in turn signals, ignition key warning buzzer, dual circuit brake warning lamp, illuminated heater controls, chrome trim on all Microbuses, and sealed beam headlamps. US spec pickups had two oval shaped slots in the tailgate allowing the rear lights to show through even when the tailgate was dropped.
