Hello! Saw a thread on this about 6 weeks ago- I am also in desperate need of the rear hardtop rear mount brackets and latch receptacles myself (the stamped steel ones that attach the rear pillar of the bed area and the rear pillar area of the hardtop together and have a receptacle that the liftgate latch catches). I have a 1971 K5 that I am just finishing a full restoration of and the single wall top has taken a HUGE amount of work (it was off the truck with a huge hole cut in the top when I bought it). I just realized I don't have the rear brackets as I am about to put the brand new looking top back on. If anyone has them or knows where I might look I would greatly appreciate it. THANK YOU!!!
