Frame Parts

[RyanKohler84]

Anyone know where I can find some frame parts. I am looking for the piece that is rivets to the frame above the rear coil spring. It is riveted to the bottum of the frame rail and is angled to the cross member just in from of the rear axle. My truck is a 68. I had too do some reapairs to the frame in this area and the rust has ate the support pretty bad. I am not sure if anyone else has had this problem but their is a gap inbetween the frame and this support and it has almost rusted the frame away. This is the only section of rust anywhere on the frame so I dont want to buy a new one. I have looked at all the websites I can think of and nobody sells these. Thanks for all the help in advance.
