Truck vs Burb vs Blazer seats

[CG]

So I see posts for people looking for this or that seats and I know some are interchangeable ... sort of.

I know a front bench seat from a truck and a burb are the same except the burb has the back of the seat covered.

My assumption is that all blazers have buckets in front (I don't know blazers).

My guess is that all buckets are the exact same. 72 blazer and a 72 truck with the same interior color option the buckets would be interchangeable in both.

Im pretty sure buddies were in trucks and burbs. I think the burb version had some sort of provision so the middle seat wouldn't flop backwards. No idea if you could get buddies with a blazer.

One of the burb back seat options (dunno which) is interchangeable with the back seat of the blazer. But I don't know if the way it mounts is the same. The frame work might be different?

It would be great to clear this all up.
