SF is for the 350 trucks and FF for the 6.5 and 454 trucks.
Not all the 3/4 ton 6.5 or 454 came with a full float. I actually think they're in the minority. My 93 had a SF rear with a 6.5

I have a clunk from i beleive the rear axle. At first i thought it was my converter but the few times ive caught it the rpms dont change. It now seems thru rigorous testing (shitload of driving) it clunks when im comin out of a corner. Its in the 50-75 mph range so usually when im runnin the old 2 lane roads between towns. Truck is optioned as a non posi but not sure if someone replaced it as i get both wheels spinnin in mud or snow. Ill save my 4wd question for after this.
Does anyone know if the ABS is disconnected from a 98 k1500 if the 4x4 will not work? There's a wire from the main 8 pin plug that says its for (4wd front wheel lock tell tail feed) pin D?
No they're differentis it possible to swap just the guts out of a gmt400 rear axle into a gmt800 housing?
If by guts you mean all the goodies in the middle then I've understood in the affirmative, but have no direct experience. Axle shafts on GMT800 are longer than the 400, so that's a definite no.is it possible to swap just the guts out of a gmt400 rear axle into a gmt800 housing?

Matching ring gear size is deciding factor for a successful "retrofit" w/o modification/fabrication; and of course matching gear ratio to your front axle for those with 4x4.
P. S. This is all 3/4 ton speak. Some (or none) of this info may or may not be applied to 1/2 ton
