Back in 67 there were 4 A body torsion bars.

Confirmed correct numbers

/6. 888/889
Standard V8. 890/891
Heavy duty 892/893
Big block. 894/895

There may have been others in 68 up

Agree. And FYI for anyone, the sizes of A body factory bars - all years - are typically:

Slant 6 .83
Standard V8 .85
340 plus HD 273 .87
383 .89

As noted above, a 1.00 bar is not OEM.
