My brothers 122 wagon had 4 wheel disc brakes, as well as a B20B engine and manual OD trans. He got it while in the Navy in '72 from another sailor who had gotten it from overseas. I had always thought the '68 122S with B20 was a rare car, and that all of the '68's had the 4 wheel discs. I was understanding that '68 was the last year they made them and they went out as a really nice upgraded car. My brother had a '65 122 sedan previously, so we knew the comparisons to it, and he always made a point of mentioning it was so special.

My '68 144S by comparison came with a B18 and automatic, 4wheel discs which was a dog of a car until I put in a '72 B20B and M410 OD tranny. He would always joke about it, citing 'old school' was better.
