seat covers

[GoMangoBoys]

I was given an almost complete set of seat covers by a member of the forum.  For the front buckets, I have 2 seat back vinyl covers and 1 seat bottom vinyl cover.  I am not sure if it is the driver or passenger side seat bottom that I have.  I need to see if I can get someone to sell me just 1 seat bottom instead of the whole set.  I will also need the back seat (both parts)
Can someone suggest the best place for me to talk to about getting just a seat bottom?  Obviously, I need to first figure out which bottom that we need.
I will also need the had panels for the back of the bucket seats.
Thanks

What year are the seats?

Legendary might be a good place to start.

Look at the holes in the cover close to the rear edge of the seat.   There will be two holes under the spot where the metal loop for the seat latch is normally installed.   There's a single hole under the location of a flat washer that's serves as a "landing spot" for a cushion from the upper section of the seat.   

The latch will be on the left for the driver side and on the right for the passenger.

On 70-71 seats the bottoms can go on either side. It is the backrest section that is driver or passenger specific.
