ys a del sol will work...for control arm. as for the bolt that keeps on spinning? i am afraid to tell you but go tow your vehicle home. ...this is what happened.....there is a welded nut (welded to subfram) that is on the end of the bolt. you have to cut a hole in your subframe in oreder to get to that nut that is spinning. instead of cutting a square shape or a circle....i woudl rec. cutting a v shape. pry thast part down to get access to the frozen/rusted nut. then when you finally get it all taken care of put the v shgape back flush with the subframe again. tack weld if you want but it doesnt matter.
