I think you mean the rivet heads are 3/4" in diameter, a 3/4" rivet isn't going into a 5/8" hole, at least not without a LOT of force.

Subject: Re: [STMFC] Pennsy X29
According to a PRR plan sheet for ladders, the X29 has
The vertical Styles are 1-3/4 by 1-3/4 by 3/16
Outside to outside the ladder width is 20
The rungs have the rivet holes 18-1/4 apart
The rungs are 3/4 inch in diameter
The rivets fit into a 5/8 hole
The vertical spacing, rung to rung is 15-3/4
Hope this helps
I am hope someone on the list may know this information. I looking for the width of the ladders on Pennsy X29 box cars so I can get the correct ladder from Pierre. I looked at the all steel book from Speedwitch and the drawings show the distance between the rungs but not the stiles.
