Are these part numbers actually different?

• HVAC heater hose - RH: 87245-6A200 (87245-6A800)
• HVAC heater hose, rear - LH: 87245-6A170 (99556-20155)

From a cursory search, it sounds like the first part number for each of these hoses is for earlier model year 100 series, and the part number in parentheses is from later model year 100 series, but are they actually different lengths/shapes/etc?

Planning to knock out Heater T's this weekend and have my parts in hand, but want to know if I should need to swap these two hoses first (I have the first part number listed for each of these hoses, not the part number in parentheses, and have a 2004 lx470)?

Disregard - did a visual confirmation of the new hoses side-by-side with the currently-installed set and they are in fact slightly different lengths.
