I have had 24 bugs, 3 buses, 2 ghias, a station wagon and a square back. I use to race the little buggers long ago. Someone way up there said something about a cut back brake, not sure what that is...but, what I did here and in Europe, was to add two levers, one on each side of the E brake lever. On the E brake lever I welded a piece of strap steel accross the bottom so that if the E brake lever was pulled up it would pull both side levers up. The brake cables were attached to the side levers. In turns, I would give it the gas and lightly (or as necessary) pull the inside brake lever and spin or drift it through curves. Driven like a tractor. I did that in 68, it may have been done elsewhere, but not in my area.
My campwagon (lol) bug only had the drivers seat. My girl friend sat on the head of the bed beside me. The rear seats were out. A platform was built and gave me a level floor. Under that floor was a cooler, where the front pass seat use to be, a stove was under the floor behind the drivers seat. I had other stuff under that floor too. Mine had the old gas heater in the rear below the back window and as I recall, it was scary sometimes, but worked great. I had foam rubber trimed out in three sections and covered, so I could lift up my floor pannels.
Since I had the rear heater I plugged up the heater vents in the body kick panel tubes. I got some rubber door molding, thin strips and doubled up the gaskets on the lower part of both doors. You had to rollthe window down to close the door!
I don't remember the tire size on the rear, but think they came off my 55 Chevy, wide snow tires, best we could do then. I did strap my tranny and bajaed the fenders, cut them out with a saw! I put my spare on the roof and kept extra gas in the spare tire well up front, but rarely needed it, but it had no gas guage. I don't remember which engine I had in that one, but all got a velocity style air cleaner.
I floated that dub down the river! We use to go from sand bar to sand bar and upthe banks. Farmers who saw us thouth we were nuts...probably were! LOL
I can tell you you don't need large tires on the front. If I did get stuck and had a half tank of gas or less, I could pick up the front end and change direction, get in and drive away. I made some skis for the front tires out of lumber (I was a kid then) and drove it when nothing else was on the streets, 18 inches in SW Missouri is alot of snow!
I had to weld up several pans, best done on the bottom. The weekest point of a VW is it's spindals, we would change over to Porche hubs and front ends in Germany.
I'm probably the only guy that had a two story VW bug. The bottom body ridge fits in the rain gutters on the roof, just put one body on top of another and had a sun roof in the bottom car. (Actually, I was hauling off an old body to the junk yard) The kid with me stood up and waved through the top window. The local newspaper reporter was out and about and saw us and we ended up in the newspaper with all sorts of questions about what they might have seen.
Other than strapping the tranny and rear of the engine with additional mounts if you're going into the air, a VW doesn't need much of anything, just lose the weight and take off!
My first one was a small split windowed 57, wish I had it now!
