I'm just about ready to order some chromo shafts for my D30 and have a couple questions. I know when installing you need to install new seals which includes the ones in the diff. Aside from taking everything apart and doing the seals, is there anything else I need to do or is this a bolt on kinda job past that?
Also the sites I'm looking at say "you NEED a vacuum block off plate," but my vacuum motor is still there but sealed up with silicone. Are these guys just trying to make more money or is that a legitimate concern?
Here are the particular ones I'm 99% sure I'm getting
