My bad, the GTI ref is based upon another recent thread; "What should I
put in my 82 mk2?" Sorry. Nonetheless believe (hold on while I
check).... Yep I was right; All 81 and later ( and all 80 and later cars
sold in California ), come with an O2. 

The 78 didn't have it. I'd recommend swapping the whole gas and
management systems over into the 78 as a unit; engine, electronics, fuel
system (the parts in the engine bay).

Thems my thinks, And I'll verify the 81 has the larger fuel dist vs a
78.
