Default 4.27 Gear in '99 GS3?

I figured I would post this here too as it pertains to the SC. I also have an SC, so I guess I'm OK posting here .

What, if any, years SC3 came with the 4.27 with a LSD? I have thought about the 4.08 LSD from the Supra, but don't think that will be that much of a difference from the 3.92, besides the LSD. Can I use the 4.08 from the Supra and the final drive from the SC3 if none of the 4.27s came with a LSD. I used the chart from an earlier post I found by slowdiver. Also, I've heard the 97-98 Supras are weaker than the earlier ones. Can anyone confirm this and to what hp rating could I expect out of each? I'm sure more than I plan to make with my car, just curious! Also, are the MK3 Supra LSDs a no go?
