How big is yours?

I am building my own Speedster chassis, just wondering if anyone can help with a few measurments. What size is the floor from the front of the rear seat to the front of the footwell and what position is the gear lever(measurment from the front of the rear seat to gear stick)?
Also thinking of making my central tunnel 7 inch X 7 inch, this is a compromise between being ridgid and looking reasonably authentic, could I get away with it being taller for more ridgidity? Your opinion is welcome.
Thanks.
Chassis is coming on well, photos to follow soon!

Check this out, courtesy of one of the guys here (can't remember who now)....

Thanks, that helps in some respects, but It doesn't tell me where the front of the rear seat is and the drawing is not to scale, so I can't work out the gear stick position.

Mick ,
Since you are doing a custom chassis, you want to sit in the chassis and find the most comfortable shifter position ....
in the shortened VW chassis speedster, the stock shift position is a bit too forward

Mine, front of rear seat to front, (brake pedal) 51 inches
Front of rear seat to shifter, 31 inches

Did this with the seat in, but tried to keep it as straight (tape measure) straight. I took it from under the seat to the rear of the brake.

If you want to increase the tunnel height just build a second structure above it. The tunnel is the primary structure. Cutting the tunnel in a longitudal direction and added two long seam welds for your finished structure will decrease the strenghth efficency by 30-40%. Additional reinforcement such as ribbing would be required to add strength in this case. It's alot of added work. The taller tunnel also will limit your bucket seat selection. Most of the speedster seats tend to flare out as the back rest goes up. Find your seats before you make the tunnel modification. If you are going to build or customize your VW frame use the Speedter body frame as a jig. I have plenty of pictures of my ongoing project in my picture folder under " Jogyver". This is all based on experience.

Thanks for your help, my chassis is scratch built, I Have not made the tunnel yet, A 10 inch high tunnel would be a lot more ridgid than the 7 inch in my design but I do not want it to look strange!!
Thanks for the measurments.

Joe, cool chassis, looks very strong and ridgid.

Is not the the real 356 tunnel kinda boxy in shape?

I think your on the right track. Does someone have anything from the Brent Johnson book on file here Like pages 118 and 119?

I wish I had squared off the tunnel as they suggested .
It would help in seat fitment a bunch.

Yes the real Speedster has a box tunnel, but only about 3 to 4 inches high.

In the picture of the frame dimensions, the front axle centerline is about 6" behind the written line as the front suspenion is of the trailing arm variety and goes behind the line of the torsion tubes. This drawing has been out there awhile and I always make sure to correct it!
