wrong wheel cylinder

If you look at my outer post you might get a clue.My 69 does not use 69 oval wheel cylinder,it looks like the 70 style backing plate so I ordered a 70 wheel cylinder now the problim my flex hose is to big:banghead:and the 70 cyl looks like it takes a steel line.I am sorry for looking daft, after this stroke and some 3 years ago i can not remember what i got.May be its time to pack it in .
