Steering shaft in my 70 Dart 5/8 inch 36 spline ???

[Brooks James]

My car is getting the front suspension rebuilt, I'm converting power to manual box.
I was told in another thread that the shaft is 5/8 ????, Seen plenty 3/4 36 spline , ???I've been all over and don't see where there is a specific listing for this situation?? I can't get to my car to measure the shaft, a heads up will be great.

Input shaft on a manual steering box is 3/4-36, power box is 5/8-36 (Chrysler proprietary spline, make sure you get the right one- GM spline does not fit).

Why has nobody mentioned the power steering to manual steering adapter? Am I reading his needs incorrectly?

Mopar PS to MS Steering Box Adapter

Ok,
Manual steering in a 70 Dart, 3/4 shaft 36 spline

Power steering 5/8 36 spline

Both are Mopar specific,

universal fitting ones will not work nor ones from other auto manufacturers

Best option mentioned, by jawbone post 3, specifically made for this application

All correct ???
