It was a Max Force kit. Don't recall the exact distributor, but it was in the mid-west,maybe Iowa, Minnesota.
There is a lot of information on line about pulling the sleeves. There are kits, but I had a neighbor with a metal lath and he had some aluminum disks about the size of the piston. Those disks were about 1/2 inch thick. He milled it down so that it had a lip and when it fit within the cylinder so the lip rested on the sleeve. Same concept as the puller kits. Then, we drilled a 3/4 hole in the center, or maybe it already had that. Took a long 3/4 threaded rod, a cast iron piece of pipe about 16" around, and a couple pieces of flat steel on top of that, and then used that set up to pull the sleeves by tightening the nuts. My handy neighbor was the key....and having a machine shop where I could get some scrap pipe and other pieces. I actually bought on line a plan for a similar contraption, but its dimensions were just slightly off, and in this job a couple thousandths makes a big difference. If you are too narrow you slip by the sleeve....too wide and you hook the side wall. But just right and everything is doable.
