where can i find a complete set of P/S brackets for my 67 i seem to only be able to find the lower bracket and not the adjuster bracket

Watch for '68-'72 big block Chevy trucks. The power steering units from them will work on the '68 back short waterpump Chevelles. The truck setup is NOT 100% correct but will be functional. The main lower bracket that has been available in the recent past is actually the truck bracket and not a true Chevelle item.
