Almost all D60's are full floaters, and all D70s are. Are you saying you swaped brake parts between one of the rare odd ball semi-floater D60s and a D70? The only truck in your sig that might have either of these axles is the 88 and to be honest I'm not sure what a 88 deisel would have, and it doesn't say if it's a dually, but it wouldn't be a D60 it would be either a 10.25 or a D70.

Tell me more about this semi-floater D60, I'm curious?

It did just hit me that the OP might have had a semi-floater D60 in his old truck and was asking about that. He didn't tell us much about the trucks did he?
