Leo, the seat belts/shoulder straps are all contained in the seat. Thats one reason I wanted this style. As for the seats themselves the 1999-2006 bucket seats are all about the same in the Tahoe's,Yukons,suburban's and some GMC and Chevy pickups if bucket seats. I will BOLT them to the floor this week and in doing I will either use BIG washers or maybe a metal strip underneath to give the seats more re-inforcement in case of an accident. I was also able to position them to where I can get the cover's off the "storage areas" under the seats. The driver side is electric and works real good.
I'll let you know how the shake down run goes by the end of next week....I hope.
