First I measured center line for both chassis. And rear axle line for both. So rear wheel would be in correct position in regards to 02 shell. This was very time consuming. Lowering and alingning 02 on top of E85 floor to see where to cut next. Then winch 02 up to make room to work. Back down again, aling. Repeat. When I got to about 5 cm from touch down I found out that my support cage was getting in way. I had to make cage to outside of 02 chassis and remove tubing from the cockpit. This was also important bcz I wanted to be able to weld roll cage roof tubes all around before I mate the two chassis. I wish I had done this from the start. Oh well it is what it is.
And we have a touch down! 02 chassis on correct level on top of E85 floor. Phew!
Very early on I knew that rocker panels would be an issue. They don't match 02 at any level. This needs to be sorted next.
