IF my memory serves ( and I've seen too much to remember everything ), there is a way to use the 73 lines you have. If you switch the calipers left and right the line will be at top and bleeder will be at the bottom. To bleed the calipers you'll remove them from the mount and lay them upside on top of the mount with bleeder up. Let them free bleed the air out, or pull the pads and put C clamps on them to pressure bleed, close bleeders, roll them over and mount them.
