Seat questions

[GeoffK]

72 suburban.

Came with buckets (not correct) and console and a bench that matched. Tall 2nd row brackets in front an two short rear brackets. Think it came from. Blazer, front buckets too.

So, on to the questions.
1. I pulled a bench from c10, completely roached, took it down to the frame. Pretty sure that will bolt right in. Is that correct?

2. I got a bench from a suburban, I thought. It was going to go in the middle row, but it has two brackets and there are four holes in floor? Nothing lines up?

3. Same with third bench, four holes, two brackets, nothing lines up. I am going to cut and weld the front legs to be 4.5 inches.

I looked at the seat thread, but can’t for the life of me can’t see how this is supposed to line up?

I was going to get a 1/8 plate and bolt that into the floor an and bolt seats to the plate. Maybe use a route to recess it into plywood?

Open to suggestions. Thanks
