I'm having a hard time replacing a fuel pump on a 63 Plymouth with a 383/auto. I can't get the bolts to mount a new pump to line up and start. I need suggestions. HELP!

Assuming you have the right fuel pump...
Past that, on the pump itself, there is a bent arm that goes into the block. In the block itself, where the pump mounts, is the fuel pump actuator 'rod'. Stick your finger into the block, at the bottom of the pump mount, and you should be able to feel it. (There's also a hex plug you can pull, that gives you access to that rod.)
The bent arm on the pump must fit under the end of the actuator rod, as you mount the pump. The rod usually needs to be pushed up, to get the pump arm under it. Guessing that's your problem?

X2 on what Miller said. Also check your fuel pump push rod length, I believe it should be 3.225". Some grease on the rod should help hold it up against the cam while you bolt in the fuel pump.

That appears to be my problem. I can't get the rod to go up to get the arm under it.

Might try seeing if the rod will rotate. But...be careful not to do any damage to the rod, since the 'fit' is fairly close. There's a chance it might be rusted...how long has the old pump been off? If you get the rod out okay, and it's in good shape, polish it up (maybe even a brush through the bore it fits into), and use lubriplate on it before putting it back in.
BE SURE to keep track of which end was against the cam, because each end of the rod will have a wear pattern, and needs to go back the same way! Rod should move freely in it's bore.

If you can pull out the pipe plug right above the fuel pump opening, that is how you get the fuel pump push rod out. Measure it to make sure it isn't worn and then put some heavy grease on it to keep it up against the cam. Now you should be able to get the fuel pump in. Good luck.

You can also try rotating the engine a bit to get the rod further in the block.

Exactly, rotate the engine to get on the low spot on the camshaft!
