How hard is it

[84 400]

well as for all of you who stumbeled across the threade i wrote about hot roddding my 85 i have some questions. I was thinking if i am gonna do it i might as well do it all and have a solid daily driver for the winter. i know it may sound like i am putting alot of time into a junker but it will be fun and my father and i will learn alot. iI was wondering how hard it is to line up fenders if i remove the front ones as well as the hood and the inners. The truck has a bad front shock mount that drives me crazy and since i was planning on repainting it (other thread) i thought i might as well clean up the frame rails. so i was thinking of pulling the friont fenders and hood so i could get at the chock mount easyer and so i could clean the frame up. i have never removed much sheet metal so how hard is it to get everything to line back up? also since the frame in back is very flackey and every time i am under there i get rust in my eyes and down my back i was thinking of pulling the bed and eather sandblasting or just sanding the hell out of it. then painting the frame with flat black and a top coat of rubberized under coating. i also thought i would paint the under side of the bed while i was at it. BTW how inportant are the cross braces on the underside of the bed? some of them are gone and i don't have a welder so i was just gonn clean it the best i could and put it back on the truck since this is a daily driver. this brings me to my last thought. the cab is very solid but the front cab mount bushing is toast. should i just pull the cab off?? thanks for the input i am planning on starting tomarrow
