45s and/or 90s

Since I can’t seem to find such a beast, nor does anybody have an idea what I need, maybe I need to change something?
Car was originally single exhaust, converted to local muffler shop duals in the 80s ( with this same axle, though it is not original to this car). Now with TTI pipes,- interference. Maybe location of splitter block is wrong for A body?
I sure don’t want to remove the axle (yet again), and then need to drill and thread a new hole, and then have new brake lines bent since I bought the stainless steel ones.
I thought about trying to use a banjo, but the splitter block doesn’t have the concentric rings to seal a copper washer. Short of a swivel or angle fitting, I suppose my answer is in the paragraph above.
