Bolt-in Bucket Seat Options?

[Mapearso]

Other than the OEM 67-72 Chevy/GMC Truck bucket seats, are there any other GM bucket seats that are a DIRECT BOLT-IN for our 67-72 trucks?

For example, do later model 73+ Blazer or Jimmy bucket seats bolt in? Would the 70s Van bucket seats bolt in?

The reason I ask is that there are multiple GM bucket seat alternatives for the 88-98 OBS Chevy pickups that are direct bolt-ins and do not require any modifications to the floor pan (for example Pontiac Bonneville seats)
