I recently purchased a 98 T&C with 112k miles.  It's got some dents &
dings, but is a one owner and has all maintainence records.  I am planning
to go yarding for the first time in several years, and I'm not really up on
this generation of vans.  I'm also not having a lot of luck figuring out
which years/models are interchangeable.  Specific needs are a liftgate and
possibly a wheel upgrade.  It appears that the liftgates through 2000
interchange - can anyone confirm?  It also looks like the bolt circle for
wheels is 4.5"?  Is that correct, and standard?  Any help or a pointer to a
good link would be appreciated.

Thanks,
Steve
