Help with a 70 Chevelle Please

[STAT303954]

Hello, I was looking to buy a 70 Chevelle and I went to sit in a 72 chevelle today with a bench seat to see if I can fit in it(I'm 6'6'). I kinda did but I was wonding in a 70 CHevelle if the bucket seats were able to move front and back. If it was not an option in 70, how much would it cost to put seats in that move fowards/backwards. Also, I noticed that there was only one side mirror on the drivers side, I was wondering how much/possible to get a mirror for the passenger side since this car is going to be a daily driver. Thanks
