Jeff,

It's not too difficult.  What you need to do is to keep on the lookout for a
donor vehicle -- an 80 - 82 aircooled that has serious mechanical problems
but has a good poptop and camper equipment too if you want that.

You'll need to buy new seals, canvas, fabric/vinyl paint if you want it look
really nice and struts if you want to make it very easy to raise and lower.
 Figure about $500 or the donor van and $600 to $800 for replacement parts.
 A weekend to remove and clean the old top and luggage rack.  Another
weekend to sand and paint them and put on the seals.  Another weekend or two
to cut a hole and install the poptop and luggage rack.

If you ever want to go down this road I'll send you some pics and we can
talk on the phone.
