Im looking to try and change my seats in my 89 K1500 reglure cab. Im trying to get away from the bench seat. Does anyone know of it being done?

Oh, and FWIW, I used to have an '89 Blazer K5 Silverado with cloth seats.
And let me tell you, out of all the luxury cars I have had (BMW 740, Porsche Boxter,
Jaguar X-type, Buick, Oldsmobile) that blazer was the most comfortable car seats I have
Ever sat in, IIWY I would try to fit in bucket seats off of an '89 Blazer - K5 Silverado edition

 

Thanks man, im gonna look into gettin some seats.. How does the buckle part of the belt bolt to? just put it to one of the ones that go through the floor?
