7050/7060 hydraulic valve swap

I have a 7050 tractor and a parts rear end from a 7060 that had the hydraulic valves and rear linkage and the cables which only one cable is good. They are the 1/4" cables and my 7050 has 3/16". I want to swap them to gain the heavier cables, a third remote that the 7060 rear has. Besides one of my remotes is locked up.

I looked on AGCO Parts and they show three different remote levers in the cab on a 7060, depending on serial number. Also there are 3 different yokes connecting the cables to the levers in the cab. The earliest serial group have the 3/16" cables so that is not applicable to me.

What is different in the 2 later serial numbers that there is a different lever and different yokes? Can I use my 7050 levers and just drill the pin hole to 1/4"? Which yokes would I need if I can use my old levers or do I need different levers and the matching yokes to make this work.

I already resealed the 7060 valves and mounted them on my 7050 along with the rear linkage and couplers and so I would like to get this project finished up. Thanks all.

Also that one 3/16" pin in the console for the tall lever..... what a pain in the arse to get that e-clip on without the proper tool. Done it before and did it again with just a needle nose but next time I WILL have the proper tool. 

Next, that same tall lever still uses the 3/16" pin even with the larger cable.... great, no change but it seems to me that if I move that hole just a little higher the stress on the cable would be less so I might do that. Anyhow changing the location of the holes on the levers seems like the thing to do to alleviate the pressure from the bow of the thicker cables. Am I correct if I do this??? Short lever too??? The thinner cables bowed easier so it seemed like no big deal but the thicker cables don't bow so easy to get them hooked up.

The shorter lever BTW has a 1/4" hole even though it used the lighter cable. The ball joint threaded onto the 3/16" cable but had a 1/4" ball stud going through the lever. I assume this was the original set up. Just an observation.  

I am able to obtain a new lever for the third remote and it is for the later, larger cable so I'm happy with that development. 

Also I see that the roll pins for the rate of flow adjustments were supposed to be indexed as per another thread..... I did not do that..... I'll figure that one out on my own but I wish I would have known that one.
