Newbie and first post, but long time viewer of the forums I have an 86 K5 that has all electric windows and this sucks. I read through another thread about how to change the driver's and passenger's doors to manual by replacing the regulators and cranks, but how can I change my rear tailgate over to a crank? I found the manual tailgate cranks on ebay, but where can I find some manual guts for the tailgate? Also, is it an easy swap, or am I looking at more trouble than it's worth? Thanks in advance!
