I’ve sent Greg details about rack. I had one made with 2.4/2.6 (can’t remember) turns lock to lock by a motorsports company, Titan Engineering in UK.
Kept original. Can recommend it, steering not heavy even with small racing wheel. If anyone else interested send me a message and I can provide details as I need to let Titan know it’s ok to use “my” drawings, which am happy to do to any Mangusta owner.
cheers
