baggin a 99 4wd yukon??

i just bought a 99 yukon about a month ago to pull my bodydrop to shows out of town and as a daily.. i have it on 24's now with 315/35/24's but its a 4wd... im thinkin about baggin it but after lookin aorund online i couldnt find anybody who makes at least a bolt on link kit for the rear... i know the front is really going to be a pain and i'll never to get it to lay out.. i just want the rear to lay and be adjustable on all 4 corners.. i want to know what my options are and if the rear of these trucks differ from 2wd to 4wd at all... and if there is a way to bag the front at all.. if not i may just wait a few months and have it stockfloored with 2wd suspension... any help or suggestions is greatly appreciated...

What offset do you have on the 24s? and do they stick out at all or do they look like they will tuck?
