First gens dont have leaf springs.They have the 4 link set up.

You can use the stock 4 link,and transfer brackets over to the 8.8,and if you are not narrowing the rear end,the tires will stick out of the fenders,which You should roll.My other comp is down right now,but I have specs that showed how wide of rim,and tire size will work with a 8.8 uncut on a stock wheel well,and what offset.

I will post specs if I can get the computer up and running soon.
