newbie, new truck, and some questions.

[jakeblues652]

so first off, i got this truck this weekend. '67 chevy K10. not bad for a 15 year old, eh?
mechanically, its pretty good. the 327 was replaced with either a 305 or 302(didn't check the numbers yet). it starts up quick. its got a edelbrock 4bbl. runs like a champ. it pops out of 3rd if you let off the gas, but what can you expect from a 43 year old truck. the floors were replaced before. and the worst thing happened.....the dash....its cut! i see why you guys always urge to at least do it right. and for some reason the CD player shuts off every time you turn on the turn signal or put it in reverse. anyone know whats going on with that? all i know is it is hooked up to a yellow power wire.
the rear tubs are rusted pretty good, and the front inner fenders are starting to. the rockers could be better but arent terrible. all the wood in the bed was recently replaced.
also, i want to add a brake booster. the manual brakes are a dog to stop the truck. i dont necisarrily need discs if i dont need them. you can tel the brakes arent meant to stop 35x12.50's. 3" body lift.

okay, i know the front quarters are from a newer one because they have the lights. any pointers on getting tubs/inner fenders or anything i might need to do/replace in the future?
