Most slant 6 engine use the spin on type filter. Also most early slant 6 engine use the long filter. When you remove the filter there will be a tube on the filter mounting adapter. Most early slants had a long tube=long filter, short filter will not fit.
Later slants had a shorter tube= short filter..but you can also use the long filter
