bilstein 5100 shock question

[66' bronco]

Hi, I am trying to find bilstein 5100 front shocks for my 66 and had a few questions. I did a hp44 full width swap and a 3.5" lift. I was wondering if all the 5100 series shocks were valved the same and if the make a longer than 21.5" shock with the upper stud mount. I can't seem to find any longer than that. And need it to be about 24" fully extended, the 21.5" would be fully extended at ride height with no extension for flex.
Thanks Trent
