You could have friction disks installed behind the spiders, you could drill a hole and tapem all the way thru the case and the spider, and put a hardened bolt thru em, or pin em is what we call it,,, you can do one side only, and ride the brake from the side thats not pinned and force em to work together,,, I would not lock it solid,,, you cant turn,,, well,, you cant turn very well unless you got 40 acres to turn it around,,, LOL! Or we have a kit that installs thru the pinion shafts with an adjustable clutch. The differential on the SM does not have to be removed for installation on the IH disk brake models with our kit. We have em for most makes and models, JD 2 cyls too! Hope this helps,, ChadS
