The bus needs light truck tires with reinforced sidewalls and a load range of at least C (and preferably D). Putting improperly rated passenger tires on there will make handling even worse and dangerous. If you need a good set of tires, I recommend Continentals (Vanco 2 or Vanco 8 ). They are properly rated, reasonably priced and also German OEM tires for VW.

What !!!      No to the tire thing.  You can't install a engine until you have a transmission installed.  If you use the Bug engine you have to either make or buy new engine tin to close up the big gap around the engine and body.
    I believe  Justin bought the tin thats in his Bus.
   I can't figure out the logic for tearing up your Bug to make a stripped out van to run and then try to sell them both.   It still will cost you more money to get the van to where you can drive it safely or at all. I may be wrong here ,but I don't believe you can get $2,500 for a '69 Bug that doesn't have an engine.  Good luck though.

The bus trans will be exspensive and rail guys love em so good luck on that.
The tins that they are talkin about aint cheap either ask Justin.
Your better off sellin the bug for a decent price and starting over with the bus...just my 2 cents. The bug could fund the bus more or less. :?

I'm seeing more and more type 1 powered buses around.  Type 4 engines are getting more expensive every day and the top of the line versions (such as a Jake Raby built engine) can cost more than a good bus is worth.

At Bug-A-Paluza this year, we probably had 6 or 7 late bays with type 1 engines.  Some had the fiberglass adaptor for the engine bay, some had a bay modification like the one I have in Homer (all the sheet metal is cut out from between the frame rails and a flat sheet rivited in with a type 1 engine bay shape cut out) and a couple just left the big gap opened around the engine.  The best way is to use the fiberglass piece.  Cutting out the sheet metal and putting a flat piece in is cheaper, but kind'a makes it hard to go back a type 4 later.  Leaving the big gap around the engine is asking for it run hot.

I'd say the determining factor is the transaxle.  If you can find a good one cheap, it's worth buying the fiberglass piece and throwing a type 1 in it.  Finding a good late bay tranny cheap isn't easy to do . . . every now and then you can find a complete bus with no engine and rusted beyond hope but still sporting a good transaxle and get the whole thing cheap . . . but like bugnut said, you gotta beat the rail buggy guys to it.
