We need Andersen sash balance for DH2856 - L8-1227 and R12-827. Can you supply these?

Thanks for posting. For the first balance, I recommend our 24-1231. This can replace balances stamped with 1227. I'm not as sure about the second balance. Let me ask you something, though: is the "8" in R12-827 a different size or font than the other numbers? I suspect it might be. If so, I think the 24-1231 will work for that balance, as well.

If you don't believe our 24-1231 will work, can you take a few pictures of the balance? I will need to see clear shots of each stamp printed on it. Sometimes seeing how the numbers are printed is just as important as the numbers themselves.
