In A-bodies the 8.75 was always a 5 on 4"
In anything else, it was always a 5 on 4.5
That Y-block has moved around a bit over the years. I had a similar issue with the fit. I just stretched the long side over to fit. But if yours is short on the driver's side,well,basically,you are screwed,lol
I guess you have 3 choices; 1) order a longer line,3) move the block, and 3) fab a new one or a patch.
The passenger side?,I just it stretched over.
