I'm Awesome
Don't half ton guys want to pay big money for 6-lug 14bsf 9.5" rears? Maybe you could buy whatever with a G80 (8-lug 14ff probably cheap, on a truck you barely drive having to carry two different spare tires doesn't seem too bad) and sell your rear to break even?
I'm pretty sure b454rat is correct, LT1 equpped full-size cars around the mid-90's could come factory with a 5-lug 14bsf 9.5" rear (I think he's right, it was part of a towing package or something). Those axles are very desirable, like the 5-lug 454SS ones - so you don't usually see them laying around.
EDIT: I was wrong, not all fullsize cars could be had with a 9.5sf - it was only a Cadillac thing (I did a little research, you guys made me curious). It was also put in Cadillac herses and limos.
I missed the part bout the 9.5 semi float rear. Those cars had the 8.5 10 bolt, like the 1/2 ton in out trucks. The 2wd 6 lug 14sf is real narrow, not the same as the 4wd axle. A building's roof collapsed week ago, drove by today as they were cleaning it out, saw a 454SS truck in there. Roof got crushed, not sure what else, but if that hits the yard, that will make the first 14 bolt 5 lug in a junkyard lol.
