Does anyone know if seats from a 1970 Bonneville 4 door will fit a 1969 Oldsmobile 98?
they look very similar. Also, can the non electric front bench be converted to electric?

is the 69 also a 4 door? If yes, then yes they will work if its a 2-door, then most likely no....
4 Door cars had fixed back front seats, regardless of a bucket or bench or strato-bench, the seatback were fixed and did not lean forward to allow access to the back, so while it will physically fit and bolt into the factory spot on a 2 door, you would not have an easy way to get into the back seat.

Just something to be aware of.

Yes it's a 4 door. Is it possible to make non electric seats electric? Maybe a matter of changing the base of the front bench?

I think Pontiac shared the body shell with Chevrolet until 1971 models came out and it was more narrow.,

Olds Buick and caddy shared thru 1970.

71 thru 76 big body gm shared the shell

In any case a tape measure will be your best bet

The seat frames will swap. The power seat tracks should bolt to either seat. If the switches are mounted to the seat trim panel (as opposed to the door panel), you will have to cut a hole and mount them in the new seat.

Consider Joe P authoritative as usual.

For my part, I can report that one of my earliest ‘66 98 projects was swapping a 6 way seat mechanism in place of the 2 way mechanism my Dad bought with the car. I believe the 6 way mechanisms came from a late 60’s Olds or Caddy. I can’t recall, and if you look at the parts, they’re identical. Good for GM in the day.

GM was really good about making these parts fit many models and years. In my experience this was especially true for options like these seats on big cars.

Some 20 years later, I wound up using ‘82 Camaro 6 way bucket seat mechanisms in my ‘66 Starfire. This was admittedly a custom effort - ( as in generous but sensible using of an angle grinder…) but it worked. Point is, within a year or 2 of your target car to receive the installation, you have a high likelihood for success.

And frankly even if it doesn’t quite bolt up, just a little creativity and thoughts about seat and seat belt safety, you’ll get where you want to go.

Continuing the quest for replacement seats...
Will 2 door seats from a 98 fit the 4 door? I'm thinking the front bench would even though it folds down, but would the rear bench be compatible?

What part of the country/world are you in? There are a couple of us with parts cars that might work for what you need. Have you created a parts wanted thread? John

I'm in Cincinnati Ohio. Good idea on the parts thread
