help needed with 904

IF (and that's one of the biggest IF's I've ever IF'ed) I get this together and working I'll be a PRO!
I'm waiting at the mailbox each day hoping the cd 70aarcuda set will arive. I'm tired of going through TylerW's comedy act ( the frying pan calling the kettle black, THE NERVE!) to get to the little parts and a lot of stuff he didn't do.
Oh, kind of square but with a sharpish outer edge?
Maybe go back to the other one then since you know you have the right stuff for that one.
