Peggy and John just finished with a new Tech Tip covering disc brake upgrades and diesel engine swaps for AD big bolts.
http://www.stovebolt.com/techtips/bigbolts/p30swap/While it is geared toward Advanced Design (1948-54) 1.5 and 2 tons most of the info and ideas also apply to 1 tons. The ideas and tips will be helpful for many "newer" model trucks, and even some older.
Sure wish I knew about this stuff 10 years ago,

probably would have done things a little differently..

What do y'all think?
Any helpful suggestions or comments?
Thanks,
Grigg
