Distributor Might Be off

So i was installing my intake today but i couldnt finish since they tip of the injector flew off somewhere, but i do have a question. I marked my dizzy like i should before i took it out. I tried placing it back in just before and it seems like it is a centimeter off to the right from the line i marked. is there anyway that i could fix this and how bad is it to be that off?

try to lift it and turn it a little bit. if that does not work you might as well re-stab it. do you have a timing light? turn the motor over to top dead center(get a 15/16 socket put it on the crank bolt and rotate until the balancer is on zero). insert distributor with rotor facing where the #1 plug wire goes. after that set your timing.
 
I always put my motor to TDC #1 cylinder when i pull the dist. Then i restab it as close as i can get to the #1 firing position and then i set the timing. There really isnt a need to put a mark. Just get a timing light and set the timing. There is no way you will get it perfectly back in and even being off a couple degrees of timing is going to hurt you.
