ok here's the deal. I have an 86' K5 I've been using as my DD for 11 years. It is bone stock but in really good shape. The motor is a new crate from GM and the trans is rebuilt with only about 3 or 4k on it. I also have a '73 sittin at my folks place in NC just rotting away. I mean this thing is bad. The best part of the whole truck is the back seat. It has stock running gear and I love the fully removable top but I can't decide if I wanna try to get it trail worthy or sell it and just build the 86. Would it be worth it to put the running gear from the 73 under the 86 until I can get a 14b/D60 or just run the 10bolts I have now/ I'm lost. What would you do? Thanks
