This retirement life has me pretty productive around the house and on the truck(s).

Noticed that my back crossmember was bent inward and suddenly remembered that I had purchased a crossmember from "thinair" in Omaha some time ago to replace it if I ever planned to use the frame. It is truly remarkable how these frames use common holes. I figured the one that I purchased would go in the same holes vacated by the old bent crossmember; nope! There are another set of holes, six inches toward the front that the new crossmember will go into. It's also nice to have another SWB factory frame laying around to compare cross-measurements with etc.

Does anyone know if I have to move the spare tire piece forward (toward front of truck) six inches as well if I plan to use it?

Thanks Mike
