Do you want it to actually be -8, or just have a -8 label? Easton's are typically over-weight by an ounce or more. A 32/23 Easton Mako might fit your needs.
Why would someone would want a 32" -8 instead of a 33" -9 or a 34" -10. Can someone explain this to me? There is a REASON a 32" -8 is difficult to find!!!
The main manufacturers do not make a 32/24. Drop 8's only come 33/25 and 34/26
So you might wanna consider a different "must have" sticker on your bat
Eric F prob had the best suggestion. Just because a bat says 32/24 doesn't mean that's what they weigh.
You can get 32/23 bats that can easily weigh at or over 24oz. Presto, there is your must have weight.
