Brake master cylinder 2808599

So "you" made me do the reasearch. My reference shows PN 2808577 ( one potential error here) with a casting number of 2225601, FOR A body.
Now if it really should be 2808599 which I see as a B body, with casting 2660909, then will be a B body deal. Also the casting AANF is same. 1" bore.
PS, I just so happened to put two up for sale on FBBO mechanical section

This is the parts catalog I'm using.
