[Big Rat]

Okay fellas, I need some input. I am thinkin come Saturday that I am goin to remove all the little things that are riveted to the frame besides the x-members. Core supports, cab supports, shackle cradle saddle support gizzies, and all the other little miscellaneous do dads and such. I guess what I am looking for here is tips, concerns, and so on. I don't want to undo something that is nice and snug where it sits only to have it not be snug enough later. I plan on grade 8 hardware throughout to replace said rivets. Thanks in advance!
