Dan,

Having had this adventure a couple of times before (on different vans) and
having just completed it on my van last month here are my thoughts.

Chances are you won't need to replace everytinhg - some of the gromits and
such will probably be good. Having said that though - you will still want to
get the entire kit and do it all at once. If for no other reason than this
is a job you won't want to have to do again. If you do everything you know
it's all new and you will most likely never have to drop your gas tank
again.

It's not a super hard job but it is sort of a PITA and I certainly wouldn't
want to do it any more times than necessary.

Most of our vendors have a kit they sell and I think they are all relatively
inexpensive. Have fun :)

Thanks,

Jeff
