For standard vibrato effects, the LFO is patched to a VCO's frequency input
(probably the linear input).

There are a few ways to get delayed vibrato (which in my mind sounds more
"natural"): the most obvious way (the best way?) is to patch the LFO through
a VCA first with that output going to the VCO FM input. The VCA is then
controlled by an EG which will control both the amount of vibrato (via the
SUSTAIN control) and the way the vibrato happens. In this case, I'd prefer to
have a DADSR or a GATE/TRIGGER delay to allow a little more control over the
onset of the vibrato.

I remember someone (Paul perhaps?) providing a cheaper if less "natural" and
smooth type of delayed vibrato using the MOTM 700 VC ROUTER. Patch the LFO
output to one of the INPUTs in the 700, patch nothing into the other INPUT.
Patch the OUTPUT of the 700 to the VCO FM input. Patch an EG to control the
point at which the 700 switches.

An additional aspect of delayed vibrato would be to use the MOTM 320 SYNC
INPUT. In fact, you could probably use the other half of the 700 to cause the
vibrato to start at the same point every time -- I bet that is part of the
vibrato on many of the older commercial analog instruments.

I wouldn't do this. I think you'd be better off just making up your own
connector cable with those .156" connectors on each end until you can come up
with a more permanent solution.
