Rebuild 1972 K10 12 bolt or swap in 14 bolt Semi Float or Full Float - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I do have a 14 bolt 9.5 SF 3.73 with G80 from a 90's SS 454 (not easily found around here) that was 5 on 5 but I redrilled for 6 on 5.5 on my 67. What other vehicles did the 9.5 SF 6 lug come out on?

They could be had from 80’s-90’s light duty 3/4 ton trucks for sure. There may be more but I know the 6 lug 3/4 tons normally had the semi float 14. My dad has a 85 K20 that’s 8 lug with the semi float 14 too, so they were available in 5,6 and 8 lug.

Thanks for those bits of info TIMCHNE. I didn’t realize they were wider. I’ve always wondered why stock they came with a wider front than rear?

Some 1/2 ton Z-71 GMT400 trucks came with the 9.5" SF in 6 lug as well.
