what is modern equivalent to sure grip grease spring type 68 8.75 gtx?

? There aren't any springs in a '68 unit..do you mean the coil springs from the cone-style differential from the '489' housing (1969)?

I think he is referring to the diff oil type for the cone style and to answer his question 80-90 will work
