[quote="delvist2002"]Will D8H rails work with top and bottom rollers on a D8 14A.If you use the 9 inch pitch sprockets?
Thanks delvist2002[/quote]I've seen it done but wasn't the best solution.
They're rare as hen's teeth but if you can find 8" pitch tracks on a EUCLIC/TEREX C-6, 82-30 or 82-40, they will fit just fine. Even the bolt pattern on the shoes are the same and if I remember correctly, even the pins and bushings can be interchanged between them and CAT tracks.
