Thanks Zoot. I see what you did (change the 65 to a 128) and move the "Low ChipSel" and "Pause 1" statements outside of the loop. I think I tried this and I got a ghosting effect on both displays. I will try this again tonight. 
On another note, to get the ascii characters to be read in from a data statement, JonnyMac has written a routine for the RoboGames badge for scrolling 5x7 characters (not in my case 8x8). But I would still be happy to use 5x7 characters but the display needs to see 64 bytes shifted in not 35 bytes. So I modified it a little and will also try this out tonight:

This way it continues loading in 5x7 ascii characters until it reaches 64 bytes and then it dumps it to the display. I don't know if this will work or not but it makes sense at the moment. I will let you all know. If it does work then I should be able to simply change the 65 to a 128 (if your original method for 2 displays works for me as well). Thanks!
