Just joined the forum. Is there a technical site? I just bought my '58 Retractable a couple weeks ago. Got a manual online, started working on the top mechanism. Can anyone help with a problem I'm having? The top linkage isn't working right,The lift jacks go full stroke but the top only starts to retract at the end of the cycle and is only about 6" off the deck when the screw jacks are full stroke. ??? Any body run into this? I noticed that equalizer bar is bent, maybe it got in a bind the first time I tried to retract it? Is the bar supposed to be straight? Thanks for any help! JH
