Suspension / Driveline tech help?

[RckyMntnKng]

Gentlemen,

Need some help understanding my next steps in the suspension and driveline department.

Ive added a set of 6" TC lift springs to my 71 4x4 Jimmy (also 3" body lift), and used a 14bff rear and D60 front. (New perches on the 14bff were installed at the same angle as the stock ones, but moved in to match the new width)

Of course now, the stock slip-drivelines from the 205 wont mount up to the new axles unless there is changes in length and/or universal joint size.

This is where I get confused on my best options....

Do I need a transfer case drop kit?
Do I need to have my drivelines lengthened?
If I do, where are the measurments taken?
Do I need to use a shim w/certain degree to correct angle to the axles?
Do i get a conversion u-joint or better to upgrade the driveline itself to a larger 1 ton matching yoke size?

Someone please steer me in the right direction, it would be greatly appreciated. I want to do this right and have it drive like its 'sposed too when its done.
