I never knew they had a 2wd sas kit either.
As for sas with chevy stuff, well good luck on that. You'd need the trans to be the right length to match the t-case and the right splines, right adapter, custom make a crossmember to hold it all, then find the said chevy front axle, make steering work, shocks, brakes al of that.
I'm sure it can be done, but not easy or cheap I bet.
