Not Your Average toggle bolts

Hello everyone, I suppose this post may set off a flurry of responses,and I hope it does as I enjoy reading and respect everyones point of view.Has anyone used or considered using these "snaptoggle" heavy duty toggle bolts?(www.toggler.com) The 1/4" size states a 1/2" hole ,(I have used slightly smaller holes) and the attached nylon plug fills the hole nicely.You can remove and replace the bolts without losing the "toggle nut" The 1/4" size is rated over a thousand pounds in concrete. I have a 1970 LY that has frame separation fore and aft.and hope to begin repairs soon. I am thinking of giving them a try on the AS,just use a fender washer with the bolts. I have used these fasteners several times on various projects other than my AS with good results.....OK....GO!...:D
