looking to buy a 60-66 help me out

[wp silverado]

im looking into picking up a 60-66 shortbed 2wd and thats about all i know right now.
ive searched around and done some researching but id really like to hear it all from you guys who have been down this road before i buy a truck and then realise i should have passed on it.
id like to know everything your willing to share from when t-bar ended and coil spring began to how hard it is to swap around if i get one or the other. also are they all 6lug? are they all drum? what rear options did they have? i6 to v8 swaps, is it just matter of mounts? one piece d-shafts or 2? how hard to stick a fat tire under? mounting a fuel cell? i know its alot and im sure its all been stated but if you have a second post whatever info you can for me, id really apreciate it.
btw the truck will be a cheap probly not running truck that will end up being a cruiseable pro street.


also i have a 67 semi pro street so im not clueless id just really like a heads up the 60-66 style trucks
