I'll admit to something embarrassing - when I built my PzH 2000 about five years ago, I assumed that since it was so "Leopard 2"-ish, it used Leopard 2 tracks, and that the kit tracks were thus waaay too narrow.
So I fixed it I made the PzH 200 hull 3mm wider - not really that big a deal since I only needed to "push" the skirts further out, and was having to remove most of the hull side detail anyway, to replace it with Eduard stuff. So I added 1.5mm plastic card on each hull side, then put all of the detail back, either via the Eduard PE or by scratchbuilding. Then I completely rebuilt the sprocket - by widening it and creating new sprocket pins - so that the Leopard 2 track (HKCW individual links - the original manufacturer of the AFV Club links) fit correctly.
I was very pleased with the end result - until I discovered that the PzH 2000 *didn't* have Leopard 2 tracks, and the kit ones were the right width.
I may well end up buying the kit again one off these days and doing the whole thing over again, this time with the Bronco tracks.
There, my shame is now known to all
