I have repaierd truck chassis in the past. two comments. The holes in the chassis are usually a 32 nd inch size, If you plan to use bolts it is necessary to drill and preferably REAM the holes to the next size 3/8 or 7/16 " .Before drilling or reaming the holes fit tempory bolts to line everything up, remove one bolt at a time drill or ream the hole and add the next bolt or rivet untill all are done. Grade 8 bolts and selflocking nuts should be adequate. i was part of a team that put about 100 5/8" rivets in the smokebox of a stesm locomotive. you only get one chance to upset the rivet . if it gets too cold it has to be cut out and start afresh.
