I used a factory style yoke that bolts to one half of the case & allows a complete rebuild plus room to install the flywheel/clutch & Press plate.
I had the yoke plugged into a stand that's avail at most chain "auto parts" (china outlet) stores. It's the one with two horizontal legs for the rollers & one vertical for the yoke receptacle. It was the most "expensive" @ $90 ish but....much more stable then the single "T" foot style &....you can slide a floor jack right in under the middle of the engine to remove it from the stand &....it's strong enough to rebuild a Detroit Diesel, if you need to.
See if you can "rent" a factory style yoke from a fellow Pelican'er.....for a case of ????
