Replacing my Side View Mirror
 

1998 Honda Accord LX.
Lost my side view mirror to a construction horse. Bought a new one and took what was left of the old off with no problem. Put the new one on, hooked it up, it works electrically. My problem is I can't get the plastic housing close enough to the small bolts to screw them back in. I thought about buying a clamp. I'm not too automotively inclined if you cant tell. Any suggestions?

Was this a honda part, or one that is aftermarket?
