Parts install question

[smokinn]

Well I recived my front clip for my truck today Thanks to Rich-White. And I was wondering what the best way to do this. Theres really no body work to do except for some sanding. I was thinking of sanding it down and painting it this winter off the truck. Or should I just swap out the old clip for the new one and worry about sanding and painting afterwards when I can put the whole truck in the garage. Because right now the new clip is in the garage and the truck is sitting outside.

Thanks
Jason
