Made one up a couple years ago for a 129 I was selling, used a Cub Cadet 2135 Lawn Tractor OEM Lift Spring 732-3093 which I got on ebay for 15 bucks or so it was close but not identical I think a little smaller ID than a normal wide frame lift and maybe a coil or two less but I also had a factory wide frame assist to copy the rest of the parts from and a local fab shop that made me a couple brackets for cheap ! It worked as well as the factory ones, the only reason I did it was that I didn't want to send my factory assist down the road with a tractor I was flipping ! If you have none as a pattern to copy then maybe not so easy ! If it's a tractor your planning on keeping then it'd definitely worth putting the assist on your arm will thank you !
