1971/72 K10 core support bolts

[cheyenne10]

back to a little wrenching. Hard to find the time.

Have a new parts kit for core support mounting. includes the carriage bolts, sqaure washers and some type of lock nuts.

Can't seem to get these tightened up. Bolt and upper square washer spin instead of nut tightening. square washer supposed to keep carriage bolt from spinning but square washer smaller than area is sits in. Nuts also do not seem to work right.

Don't think its just a 4x4 issue. Always had trouble removing old ones with spin, rust, etc but these parts are new.

Whats the trick. It must be simple.
