Thanks for all the replies, it has been quite a task trying to get the old broken grousers taken off the track. Lots of pulling, pushing, prodding, punching, grinding, welding, grinding, painting. And of course the bloody knuckles. Looking like I may need to have around 25 to 30 grousers made up. One side is definitely worse than the other. Another thing I noticed when looking through the forums Was An Old Post of 2 1950s Trackmasters and the tracks rolled up next to them all the grousers looked in great condition. The two units were located in the Northwest Territories. Ring any bells.? Here's a couple of pictures of the grousers I've redone Thanks again Ryan
