Installing 3'' drop need answers

hey sup new here but looking for possible answers i got a 99 ext cab dime with the 2.2 4 banger and im lowering it 3'' all the way around curious about if im going to need to shim my drive shaft and stuff not quite sure how to measure the angles? any help would be appreciated. hit me by pm or even post here im am going to go start install here ina little bit so anything before hand would be helpful

u shouldnt need to with a 3in drop

with a bigger drop ext cabs are hit or miss. i had mine at a 5/6 drop for awhile with no shims and had no problems but others with the same drop needed to shim it.

u will be fine with no shims with a 3in drop

kewl thx bro preppin to do it kinda worried cuz i only got 1 jack lol anyways wish me luck check back ina bit

ok drops done.. not to shabby took quite awhile being i kept runnin into probs lol like stocks had to be cut out and a few other quirks but anyways it looks/rides good so far will post pics asap.
