Stop in for a cup of coffee

So --- I'm thinking about doing Tee Shirts....

2 questions...

Should I just do one with the FABO logo on the left chest or do I need to do something more involved? (like "Got Mopar" or "If its too loud, Your too old" on the front and the logo on the back)

Second question. If I do something more involved like I mention above, would it be a problem if I included 3 sites on the back? I was thinking FABO, FBBO and FCBO with the tag line "The ABC's of Classic Mopar"
