The best place I could steer you to is the NTBA, its a national club for just tbuckets and when I built my first T, it was a huge help.....here are some of the common links for Tbuckets....there is a shop, Hot Rod Alley a couple of blocks from me, Frank Hogan is the owner, he can answer almost any question you have as well as stocks a lot of parts..his number is 817.268.3717, tell him Adam sent you....here are those links, but check out the NTBA, great source for info and help
