Not sure where this question belongs, but...
I'm getting ready to install the steering box and brake/clutch pedal assembly, and need to buy new nuts and bolts. I'm planing on using grade 8, but I don't know what sizes to get. I have the assembly manual, which shows the nuts and bolts, but only GM part numbers, not sizes!
Is there any list or code showing size compared to part number? These things are a bit too heavy to hold in place and try to measure!

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
