Which front brake hose lengths to buy 19" or 21-1/4"? Part numbers inside

Hey all so going to be redoing my front end suspension and after watching few more vids and getting info from other members on the board i was informed i most likely going to need to get new brake hoses in the front.

I went to look up what they had on rockauto and it is filled alot to choose from.

mainly it comes down for me to two brands, but they have two different sizes? One is 19" length for front right or front left, then another is 21-1/4" in length for front right or front left, part numbers as follows

Ac Delco 19" Ac Delco 21-1/4"
Front right- 18J340 Front right- 18J617
Front left- 18J290 Front left- 18J618

Raybestos 19" Raybestos 21-1/4"
Front right- BH38252 Front right-BH38602
Front left- BH38181 Front left- BH38603

I have 88 firebird (originally formula ws6 suspension if that matters), im curious as to which length would you buy?

And would be going with the 21-1/4" just to be safe cause any harm? Will i be able to drive normal with larger hose if it happens to be larger? Thanks all for your input and advice

The longer hoses should be the 1le style hoses. You might be able to use them as far as length but I don't believe the banjo bolt end is the same shape as the one for the standard brakes and may not seat properly
