Koops rear outer driver's side bracket won't fit if you drill the driver side 3/4" over from the front outer most hole. It was off by about 1/2" from where my bucket seat tracks holes needed to be drilled. It needs to be in the 1-1/8" to 1-1/4" over if measuring center to center.

Can someone with buckets in a truck please measure center to center the distance shown in this picture. Or maybe Koop can answer how far he moved his over.

Thank you.

I hope this picture didn't steer you wrong. I used 3/4" because it made my driver seat position match the passenger side. I didn't want a bigger gap between the console on one side or the other.
Please post the information you come up with here. thanks

Hi Mike,
You didn't steer me wrong. I measured my seats at the 3/4" position and I agree that it puts them in about the same position LH & RH. I just had to modify the rear outer bracket to fit the holes.

I was just hoping that someone could give some concrete dimensions from a bucket seat truck so that it could be used for future reference by all the guys on here doing this. What you started with this thread and what you did with your install is great info to have!

Thanks David,
I think we are all learning from this thread. I really don't understand all of what GM did on these trucks but the more I learn the more I find out I don't know.

how come the member who is selling the outer rear brackets on the parts board is not commenting? Read post #72 about the fit. Just sayin...

I took some pics of my 1972 C30 which has 44,000 miles on it which has factory bucket seats in it. Like this truck and all the trucks that we have seen bucket seats in, none of them used the bolt in the support that runs underneath the floor.

The front bucket mounting just used a square nut welded to the floor. No additional floor support brackets was used except for what was used for the bench seat. I will take some photos of the front mounting and add them later

As for the offset on the drives side front holes I found it to be 1 1/4" to the left. See photo.
