i went to Sears yesterday to look at them, but the one they had seemed highly inaccurate. the needle wouldn't move until you moved 3 or more degrees and then it just swung over. i bought a T-Bevel which should be some kind of help.
i've got most of the rear end ripped off. decided to pull the whole arm off (it mostly has to be released anyway) so i can relube the inner pivot bushings. they, or could be the spring plate bushing, were squeaking like hell. going to paint the rotor hats too. they are already rusting. my left spring plate/torsion bar has always released on the inside first. makes adjustments a real pain. i have the added pleasure of having my fenders on now. i'm going to have to pull the left one just to get the bar out. so much for all of that fine tuning to get the lines to match.
figured i would take this opp to go over everything though. going to retorque everything underneath. finish up some wire covering. have to adjust front bearings (too much play). still need to get the shock tower plates welded on too. install oil temp sender finally. paint tailpipe (still need to find tip).
that should cover it...for the underside. still have many small items to take care of up top.
