Dana 44 Pinion Angle

To complete the Dana 44 swap into my 97 TJ, I know I must adjust the pinion angle. I also know that the best way to do this is with adjustable rear control arms. To the best of my knowledge, Rubicon edition TJs don't have adjustable control arms, so how is their pinion angle changed? Are the control arm brackets welded on at a different angle? I know the transfer case and drive shaft are not the same as a 231/D35 equipped TJ, but will these changes cause the pinion angle to change? Thanks, just looking for something besides the control arm option.

The adjustable control arms are aftermarket . None of the Jeeps come with them

Only other option is to cut and move your CA brackets to get the right pinion angle... I'd get adjustable CAs before doing that.

What driveshaft are you running? For a stock driveshaft, output angle of TC and pinion angle should match. This requires less adjustment of pinion and is the setup the factory goes for with stock fixed arms. If you are running a CV driveshaft then pinion angle and driveline angle need to be the same. Adjustable control arms probably the best way to do that.
