I'm expanding my existing garage out the back. When building my temporary cripple wall to support my roof trusses prior to removing 11' of the back wall and installing the new header, can I space the cripple wall studs 24" o.c. or should I space them 16" o.c.? There's only attic space above, no second story of the house to support. Thanks.
If it is temporary I don't think it'll be a problem. Just make sure that you have meat on top to prevent the top plate of the temporary wall from sagging between the studs under the load. Two plates would be an absolute minimum with 24"oc stud spacing, even for a temporary wall.
