Use a 1" spacer between the frame and crossmember and see how it is.

This is the set up I used.
It's from Rancho if I remember correctly.
Paid $50 at the local speed shop cause I wanted it that day. Look around on line and you can find a cheap set up, or make one yourself.

You can also get a spacer for your front driveshaft

Well guys I have talked to a bunch of the local wheelers around me and every single one said Dont do a tranfer case drop unless ya wanna go through trannys. This makes sense because when you drop your transfercase your tranny is now on an angle and the tranny filter is near the front of the pan so there is a very high possibility for them to blow due to not getting enough fluid. Any one heard a this before. So my new plan is to drop the motor mounts 1-2 inches as well as the transfer case to keep everything factory again

I have heard of lots of people with a 6" lift, but I have never heard of anybody lowering their motor mounts to make it work. How extreme of an angle are you talking about?

its pretty extreme i think, and im not blowing through u joints. its on an 81  k5 blazer so is got a real short wheelbase Also as soon as I flex the rear the wheels my drive shaft is sooooooo close to fallin out a the transfercase its not even funny. and I would rather lower the motor mounts as well as the transfer case to keep everything level and keep my drive shaft angles low.

I wouldn't be worried about lowering the t-case an inch or so. If your driveshaft was longer and you had more of the yoke in the case the angle would decrease. It sounds like you just need to drop it that inch and then have new shafts made. I bet you'll find alot of play in the yoke, and that the t-case rear seal leaks now too. Post up a pic of that angle and the yoke if you can.

So its not binding just seams to short. You can sling the springs around and that will make up 2 or so inches

That's ridiculous! What happens when you go up or down a hill? Does your trans blow up? Don't listen to whoever told you that. Put the spacer in and make a mark on the shaft slip yoke with the suspensionfully extended Then measure it.
