Well, going to hold off on the trans for a couple weeks. Just pulled the 4-speed out; hopefully picking up an engine hoist tomorrow morning and then pulling the motor.

How difficult is it to remove the locker from the KS10?

Anyone know where to get a drain plug for the rear end? It is 1” diameter, fine thread.

Re: KS10 rear end
 

Here are my thoughts on your situation. I would try to locate a later rearend from a '70-'72 Chevy 3/4 ton truck. Most have a coil spring suspension like your truck. More than likely, the rearend will have 4.11 gears. I had one years ago with 3.54 gears.
Using this rearend, will be a direct bolt-in with the exception of the panhard bar. As stated earlier, the later rearends had a boss cast into the upper right corner of the center section for the panhard bar. In your case I would buy an aftermarket panhard that has it's right side mount on the right side trailing arm perch.
Another consideration, the drive shaft might not be the correct length.
I don't think you would like 4.11 gears using your stock transmission. Too many RPMs at highway speeds. An overdrive trans is the cure but pricey. No way would I use a T5 transmission in a 3/4 ton, they are pretty weak and can't stand a lot of torque. An NV 4500 out of later trucks would be a good choice for a manual but they are pricey and very much in demand.
It depends on what you plan to use your truck for. Just cruising is one thing, but if you plan to use it as a truck, put it together with the heavier components.

This would work, right ?

Out of a c20, not sure what year. 14 bolt.

Re: KS10 rear end
 

Yes that will work if you don't plan on hauling heavy loads. That is a semi-floating 9.5" 14 bolt. You will need to weld on the trailing arm mounts and a panhard bar mount. I make both of those. With that said, I agree that to achieve what you are wanting an OD trans is needed. In my experience the Eaton HO52 is often times a noisy differential.

Re: KS10 rear end
 

Thanks Captain, can you post pics of those and prices? Trying to get an idea of what I am dealing with.

Re: KS10 rear end
 

Here is the for sale thread for the trailing arm mounts.

I do not have one for the panhard bar mount is it is quite new. I have only sold 2 so far. The cost is $39.50. It is basically a copy of the factory bracket.

Saw a Dana 60, 14 bolt, 8 lug I could possibly use in my truck. Only thing, it does not have the drums. Are the drums easy to find?
