Hello, well I'm just about finished putting the front end back together on my 70 challenger and just wanted to make sure on a few things. First, is it ok to put the torsion bars in before putting the spindles on (so I can get the LCA as low as possible to index T bars) And then just put a jack under the LCA to raise it so I can put the spindle on? Also on my new spindles it says to take off .0004 with 240 grit sandpaper to fit the bearings. Is this normal with new spindles? Thanks in advance
