>> 46mm is the key. This will leave you a little +/- which will be absorbed by the insert nut at the top of the housing.
>> Before you cut anything, score a straight line on the housing where you will cut. This will allow you to use the line for alignment when you are welding. It's important to keep everything lined up.
>> There is +/- 1-2mm space inside the housings for penetration of welds.
>> This is all basically untested. Don't blame me when you crash / die. Do blame me when your car is slammed on the ground and looking oh so sweeeet.
>> Hints for cutting and marking: Use masking tape wrapped around the housing as a guide for a nice straight cut when removing the 46mm section.
>> Really do score the body to show a straight line for keeping the steering arm at the correct angle. This angle is pretty critical - a bit can be overcome with tierods, but not a lot.
