Started working on the track upgrade yesterday. I'm drilling out the cast pins and thru both part. Then 1/16" piano wire goes in place. The two pictures show the slop due to wear of the pins cast on the original pads. I was able to remove a complete link and get the track back on, it was too tight though and I didn't run it that way.





The short top section is what I have done so far, just started.

Its nice there is enough metal on the links to add pins... How much running did it take for the tracks to get loose? Are the drive wheels holding up ok?

I'm not totally sure about the time but I estimate 4 or 5 hours. The nubs cast on the inner part poked into the hole of the outer tread in front of it. They were never that tight to start with.

Default Roller chain with tabs for track pads?

What/where should I look for roller chain with mounting tabs for building tracks if it comes to that?

If I understand and measured correctly, the original tracks measure 3/8" pin to pin. And 1/8" wide inside.
