73+ Bucket seat hole dims

[swing69]

I'm going to mount some buckets in my bench seat 73 Dart. I found the little dimples, and here is the dimensions that I got from it.

I think this is right, going by memory; Front to back hole length is 12.00". The driver side spacing between the two rails is 12.75" and the passenger side is 12.25" between the rails.

Can someone confirm this? I want to make sure I've got the dimples and not a spot weld.

Also: 1) can someone tell me the side to side offset of the seat WRT the brackets in side to side dims for the drivers and passenger seat?

2) Can some tell me the rise of the front vs. the rise of the rear of the seat rails above the floor? I need to set the seat height.

thanks

the spots should line up, you might have to look from underneath.

Grab your seat and sit it in there and see if you can line the seat track studs up on the dimples.
