Fuel injection ready tanks are nice.
If you want to stick with a stock tank you will need to make sure your sending unit has a provision in it for a return line, or you will need to modify the tank.
I would not go with a '71 style tank. Go with a '72+ tank. Read my reply in this thread from earlier today in regards to that: My Gassy-Smelling 71
I don't really understand this statement. I just switched from a '71 filler neck/cap to a '75-76 (same as '72+ just unleaded style) filler neck and cap. It doesn't stick out of the body anymore than the '71 did.
