i put a '64 chevy c10 onto a '78 chevy suburban frame wasn't really all to hard just had to use some 2x2 square tube as shims original intent was body lift but i needed to use two stacked plus the body mounts from the suburban in the front for the core suport and just a single 2x2 for all four monting spots for the cab and then for the bed just the front 4 mounts need a 2x2 and the back four are just on the frame i also had to cut off bout 8 in. of frame on the back cause it stuck out that far. big thing is to take all the mounting brackets off the your 66 frame and bolt them to your new frame (core support ones can be left on just need a plate to move the hole back? i couldn't relocate cause the powersteering gear) and my clutch linkage is all rigged up cause i couldn't find the right parts so i used several pieces from differen't trucks, you'll also have to shorten the steering shaft 1 in. give or take a hair if you use the original column not sure what you'll all have to do to use a newer one.... any other questions feel free to ask i can get pictures for you but it won't be till next weekend when i go up to mom and dads for a visit (currently living in wisconsin to go to college) i should be able to answer most questions i did my build on a budget i just used what i had and maybe spent $100-$150 for other things also i sacrifcied power brakes to eliminate the expense of asprin it still stops just fine so i have no complaints on not have power brakes i hope this all helps if i forgot anything or if theres something missing just ask and i'll give the best answer i can and i'll get a bunch of pics for you next weekend
