88-94 low back bucket seat question

[DBear]

Probably an odd question...anyone that have these seats in their truck, could I get a measurement? I have 2 bucket seats, different colors. I noticed that the 2 main brackets are offset under the seats, and they are offset the same on both, so not sure if they're set up for driver side or passenger side. They do have provisioned an extra set of holes to move the brackets over. So, I am looking for a measure from outside of the bracket to the outside edge of the seat. Thank you for any help you can provide.
