Exactly what I thought ... any way to slope the leg of the L to get it
at the junction of the redials?

The single most important thing Joe said was:
<<<< The antenna feed point terminates at a four foot ground rod and
then I am running a number 14 wire from that ground rod to my existing
radial field. That run is about 40 feet. >>>>
Joes has virtually no ground at all on 160 meters, because his
system's ground connection to the radials is via a single #14 wire 40
feet long.
A 40 ft long wire laid on earth to the radials, even if Joe had 50 x
100 ft radials, would almost certainly make the ground path impedance
hundreds of ohms.
Joe's antenna virtually doesn't have a ground connection to radials at
all, and this has almost nothing to do with the number of radials or
type of radials. It has to do with the 40ft long connection.
