shocks and traction bar

ok on a 86 camaro it took me about 2.5 hours to put in drag shocks and a traction bar, alone in a cramped garage would that be considered a moderate or easy thing to do with limited tools and alone within 2.5 hours ? and how much harder would it be to put in a 7.5 to 8.8 rear end in a 1990 4cyl 5 speed compared to what i just did

thanks
