Welcome aboard, benny6. Either you or a pvs. owner must have really spent some $$ in beefing up that '61 to have a Dana 30 and Saginaw steering. Sounds like you've got a gem of a Jeep! Photos?
Saginaw steering was introduced on the CJ5 in '72, so that eliminates pre-72 linkage. Different links, joints, etc. I don't believe that any linkage is interchangable with the B.S. ("Before Saginaw") Ross steering. It's a good thing, though, because you're more likely to find parts for your getup. Let us know if you need resources!
