noob introduction, couple questions

[Flyer]

Hey Guys, found yer Site through recommendations of friends. i have a '68 C10 longstep. i'm planning on swapping cab & front clip to a 70 shorty chassis. i found this thread on cab removal: http://67-72chevytrucks.com/vboard/s...d.php?t=196293 cool info... i'm wondering if i can get a few pointers on the bolt removal... do i need to remove the cas tank to get to the rear cab mount bolts ??? i see a bolt head underneath thr cab, but no nut... i'd like ta hit them with some liquid wrench... the fronts i see the nut side is down... is the head of the bolt under a cover plate in the cab ??? i have my carpet (rubber mat) up and i don't see a bolt head... maybe i need to look closer ???

also, please... the front of the shorty is discs... 5 lugger. my differential is a 6 lugger. i'm thinking of having rear axles redrilled for 5x5 bolt pattern to match front... question... i'd like to get a recommendation on a rear disc set up... i'm thinking of trying to locate a 79-81 Caddy DeVille rear disc set up for my 68/70 combo... any thoughts about this ???

here's a shot of my 64 Chevy II (work in progress, 377, TKO600 10bolt Heidt's clip... blahblahblah )



and here's a shot of my 68, it may look rough... but it's in pretty solid shape. i've owned it for about 15 years

it's gonna be a 327, M20 4 whl-dsc... lowered....




i appreciate all the help i can get... i'll be pesterin' ya often and pickin' yer brains...


Thanks !!!
