Need help with rear bilstein shock order

So i have a 2001 Tacoma SR5 TRD 2WD double cab. I ordered the bilstein shocks for all 4 corners. the 5100 height adjustable for the front and i asked for the 5125's for the rear.

is it a problem if both rear Bilstein 5125s are the same length?
heres the part number: F4 BE5-6253-H5

thats the part number on both the rear Bilstein 5125's.
ive researched before ordering and was expecting to get one that was just a bit longer than the other. But from what ive researched that part number means they are both 8.5" long. Ive seen lots of people say that one should be 8" and the other 8.5". Since the company sent this, im hoping they new what they were doing? Is it different for 2WD tacomas, can they both be the same height in the rear?

Heres my total suspension lift that i ordered...
-Bilstein 5100 height adjustable in front
-Eibach 3" coils for the front
-Bilstein 5125's for the rear
-OME/ DAKAR 2.25" leaf pack springs (not AAL's)

im hoping the rear shocks they sent me are correct and will work? let me know what yall think.

thanks!
