I rebuilt a set of Type 3 track back in 2005. I used a 220 Arc Welder and Carbon Rods to blow the rivets out. I turned the amperage up to the maximum then just touched the head of the rivet. GGSZHTT, and the rivets were gone instantly. I burned the outer 6 rivets on each grouser out which took about 2 minutes on each grouser. Then used 3 ply conveyer belt material, grade 8 bolts, fender washers and poly-lock nuts to hold everything together.
If I had known about the repro bands then, I would have bought and installed them instead. If I ever run into another weasel again and can buy it, I will go that route next time.
