Can you crack the code?

So I've taken a recent interest in cryptography, ciphers, and codes. It's so interesting to me that with very little information, some people can crack the most complex codes and decipher hidden messages. After a little bit of reading online, I was able to come up with one of my own, a mono-alphabetic substitution cipher. It's not very in-depth at all, but I thought I'd mess around with it a little.

Here are the hints:
1. The key word is "Tuesday"
2. It is an Edgar Allan Poe quote.
3. The spaces in the code are not the spaces in the actual quote.
4. There is one number in the very last group of characters that is just a place holder, and isn't an actual letter in the word.
5. You will not need to use "zero" at any time. There is the letter "O", and the numbers 1-9, but there are no zeros anywhere.

Here is the code:

6S86R A8L8X Z5AYY SA118 RYF6Z XT5QD J868X 8YYFX 1AYAF JJ3DR 8E8RY YZJ8X T865Y F3ZXL Y5Q86 SZXLO SZTSZ YX568 H8R36 SZXLZ 6YS5A J1M89.


If you don't know what a mono-alphabetic substitution cipher is (I sure as hell didn't until I looked it up), you'll probably want to find out before you start this, or else it might be a little too difficult. Or maybe it won't be. If you have questions or want more hints, leave a comment or send me an IM or something. Let's see who is the first to figure it out...
