Marshall,

Well it's best to find out from a competent shop what the van's real
electrical problem is first.  If faulty diagnosis is found, then have
the repair shop's invoice or memo reflect what the symptom and  problem
were.  For example, Checked and found no voltage to the load reduction
relay, causing a no start. Replaced ignition switch.

Then discuss this with the shop that charged you for a faulty diagnosis
and unnecessary R & R of a new starter.

As far as what to ask for?  Well this just my opinion with a couple of
variables. Number 1 would be to pay only for the wholesale cost of the
starter, if your starter was more than a couple of years old and you got
a good starter for the $367.  If it's just a poor quality repaired and
repainted job, I'd consider asking for all of my money back and ship
them the starter that they installed. Then have quality starter
installed.

Sincerely,
