steering rack I decided on Strange engineering 12:1 ,they use them in sand buggy's and drag rails.
I will be extending the end by using a linier pillow block 106mm long mounted to the front .the rack will have some form of link to a hardened shaft 20mm dia.
The brackets the rack is mounted to will get flanges attached to up the rigidity,I have not done this before so I will have to work out the bugs.
I dont want to make a rack specific to this car.
Thats all for the moment.
