Whar seats and bench will fit in a 79

My 79 chevy has a front bench seat.
That would be OK but I'm 6ft8 and my wife is 5ft2.
So when she is driving the truck I'm almost sitting in the glove box.
OK when she's driving I have had a few to many beers to drive, and the simpelest thing for her would be to just trow me in the bed.
But I want to change out the front and rear seats.
There are almost no US trucks here to find in the junkjards here in the netherlands, so I need to get them from Ebay and have them shipped.
Can I take any newer Tahoe, suburban, 3500 seats and bench or wil I have a problem getting those in.
And how about ford or dodge seats.

Thanks
Remco

I would think most anything would fit, dont know specific vehicles that would make a good swap though. sorry.

What do you mean by "fit". Physically or bolt in?

I mean Physically.
Not to wide or to narrow.
