1010 gas timing mark location and specs

[terry419]

Found location for serial number on block from last post,but tag missing.Still need location of timing marks and specs.I think the marks are located right side bell houseing under cap and still need spec.Last owner had pulled distributor and I wanted to check timing.I noticed a oil leak at the right final drive gear cover.Pulled the cover and found remains of a bearing.Looks like some serious repair .
