Looking for a basic air bag kit for my 65 stepside

[Lowandwide65]

Been searching like crazy here but since I have very little knowledge of air suspension I am still very lost. I am looking for a basic stock location airbag kit for my step side 65. Don't mind converting rear to disc or changing to higher lug count if I have to but I would like to just keep the stock control arms. I am not looking to make a show truck just something that can get as close as possible to the ground (love to lay frame but that looks like it cost a lot more than I am willing to spend). Rear is leaf springs and front is obviously coil. I would like a side to side movement, front, rear and up and down. Basically I would like to get bumpers and doors as low as possible with out all the fancey parts. Just want and nice very low hot rod that I can raise and lower at will. I don't mind piecing it all together, but a kit would be a lot easier to me. I took a look at brothers trucks but the tank and little parts don't seem up to par. From searching around I need at least a 5 gallon tank. My budget is a max of 2k as I need to save up to fix everything that the thieves messed up after they stole my truck. Anything helps guys. This was my first vehical so I am looking to finish what I started before she was stolen from me. Not sure what exact info is needed so sorry if I left out some obvious info. I am coming off from a fresh 87 mustang big block build so my Chevy truck knowledge is very rusty haha.
