ac and other questions / problems

[Dirtkid93]

i have a 1964 chevy apache c20, didn't come with ac from factory, or radio. so obviously the ac where i live is a huge deal but currently its a little out of the budget i have, trucks already been converted to 12V. what is a good temporary ac fix? would anyone put in a fan? also being it didn't come with a radio, i would have to completely wire and install every component. the seat has about 6 inches of space to floor pan. has anyone fabricated a sub / speaker box that fits under there? ( yes i could always get kick panels, but lets be creative ) and lastly is the wooden bed is totally dry rotted. the cheapest thing i could think of is to buy composite board ( deck material ) and cut it to size and replace the wood rails. is this a good idea to do as a temp until i can truly afford to do everything correct? truck also has a inline 6, 230 3.8 liter. 4 speed manual ( granny gear included ) should i get it regeard to remove the granny? or would i have to get a whole new tranny? 2nd literally gets me to a max of 12 mph then its a mid 3rd and extra long 4th

now if anyone knows a thing or two about cb radios, please answer this as well, i want to run dual whips off of my truck, was looking at cobra 29 ltd with weather, PA, night watch, or a galaxy ( not sure if thats too extreme ) but whats the best rout to do what i want?
