1970 CST w/ 402 Big Block - Barn Find

[GMCNUT]

Hey guys; for 20 years or more I have always been just a 55-66 truck enthusiast, but being close friends w/ fellow member and long time 67-72 truck guru "JQ-72" on here, I have gained some knowledge and exposure to these later models you guys love, and I sort of thought to myself "if I ever stumbled over one of those with enough of the fun goodies, I would buy it for myself to keep". So looks like that has happened finally. I just stumbled onto a 1970 CST longbed w/ numbers matching 402 still in it and T400, w/ fact A/C, PB, and PS. No uber- rare stuff like buckets or tilt, but just a real nicely equipped truck in general. This truck was in a local barn since the 90's and while its always cool to find a well preserved low-rust truck in a dry Alabama barn, the issues with barn finds are that sometimes there is a reason why they are in there imobile.
in this trucks' case someone in the family had a need for the big-block A/C and PS stuff and robbed the brackets, pullys and compressor & pump themselves off it. I checked the truck over and also discovered the right hand exhaust manifold has been removed too. Thankfully the radiator and special big-block specific fan shroud are untouched, and so is everything else under the hood except the missing air cleaner. So, knowing very little about these trucks I immediately called Josh (JQ-72) and he did not have any of these BB specific parts and suggested I contact the members on this board for help. So, if any of you have any of these parts you can let go to a good cause I am willing to pay a decent price as needed to acquire them so I can see if I can get to where I can drive this truck. Josh says I need short water pump 396 / 402 A/C pullys and PS brackets & pump - he said all 69-72 402's are short water pump engines, so please know you have the right stuff before PMing me as I only have Josh and you guys to identify what is and is not correct - I am a fish out of water messing with a 67-72 truck, but greatly appreciate anyone's help to get life breathed back into her!
