I am going to do mine and would like some ideas. I was considering doing something like what HR parts n Stuff has for the G bodies and adding a vertical piece between for added strength. What about using the edelbrock brace that ties the front upper and lower points together ?

Rob, I made similar braces for the LCA mounts on my 65. I have pics if you are interested, PM me your email address.

Rob, I Use The Edelbrock Pieces On My Car. Work Great So Far.

Ask this in the Wagons forum. I beleive FOFIDDYFO has done some extensive chassis bracing.
