Ok need some advice.

Doing a 200tdi swap into a Series IIa (left hand drive). I want to put a new galvanized chassis under it with the leaf sprung suspension. I don't want to have to cut into or weld my new chassis. I need to add power steering.

Keeping this all in mind what trans and t-case and axles can I get away with? LT77/LT230? What can handle the power?

Who makes a chassis that will work with this all? Anything I am forgetting?
