Big John gonna karate chop that thing in half? (IMG:style_emoticons/default/smile.gif) Those are some long rear suspension plates on the 550 frame. Looking great.

I told him to use his laser vision.

Yikes - 5 inches is a lot!

I may have to shorten my femur's! I'm glad I'm not a tall dude, because tall and 904 don't work. I'm 5'9" and I look squeezed in this real one 904-0014.

Ok, scary day, big cut done, it is currently two cars. We chopped the 5 inches out and you can see it's now as tight as a 904. Look for more updates on Monday when we seam it back up. Glad this part is about to be behind me in the build, I dreaded this part.

Wow that's tight. Maybe you can sneak in another inch or two by denting in the lower cross member behind the seat? Go-cart for sure.

I have a couple of tricks I can do to squeeze a little more room out. Instead of a Speedster seat I can use a Spyder seat, they are smaller.

Prepped the two pieces of the car to go into one tomorrow. Everything is lining up well and fitting nicely. Stay tuned.

What was once two pieces, is one again.

Reunited, and it feels so good!
Now we are back to normal stuff like trimming out the front fenders and fitting the body, no more scary parts.

Sitting in the car is tight, but it feels as tight as when I sat in a real 904. My brother is 5'6" and sat in it, it is much more suited for him than me at 5'9".

Here are some pre-welding shots, to show how tight we got it.

That is a small space, wow.

Before you go further Adam you really should do a string alignment with special focus on toe and wheel position. It’d be a shame to get everything else fit up and find out that the center of the car is at a slight angle which results in a crab walk which can’t be adjusted out.

Yeah,
I'm loving it.
The front steering geometry has now been altered, the instantaneous and imaginary, intersections must be recalculated, determined.
This is the part where it becomes interesting, to emulate the performance of the factory design, 60 years later, with computers.

Cameras mounted at the corners to analyze tire contact patch, while testing, the motions, the heat transfer by infrared.
That will be fun, enjoying the build, hope to hear it make nice sounds.

One option to address seating position would be to shorten the steering column and move the pedals forward. I've done this to 911 and 914 racecars now. A bit of a PITA, but really helps with the seat position.

Stan,
I think you're onto something. I consulted with a friend of mine last night who owns 904-0014 and this is what he said,
"The length is adjustable. Since 904 seats do not adjust, they made both the steering and pedal ass'y adjustable.

Attached is a page from the 904 parts book showing the steering.

When you are strapped into your seat, you should reach out above the steering wheel, drop your straight arms down and your wrists should touch the top of the steering wheel. That allows you full control of the car w/o taking your hands off the wheel."

I might have to entice you to head upstate to consult with me!
