Hi all, I'm trying to install my wiring harness in my SM 335 kit. I'm having difficulties pulling up my first component which is the input jack. I gave up yesterday in frustration and plan to try again tonight. Stew Mac recommends a couple of helper tools they have, one to hold the pots from underneath and one to plug into the jack to hold it tight while you screw down the nut. Are there any tricks to doing this part of the job without those tools or am I better off to order them and be done with it? I did/am trying rubber bands to little avail. Thanks so much!
