AMC Mod 20 wide track help

Hi Fellow Jeepers,
I grenaded the AMC 20 in my 84 CJ7. No I wasn’t on some crazy trail or remote desert location “Thank God” It was in the parking lot of my local Starbucks. I Know, Don’t say it, at Starbucks.

As I understand it the Track Lok system is inherently prown to failure after years of abuse and in a 28 year old vehicle it was a matter of time.

My plan now is to install one piece axels, new bearings and seals, re-gear to a more appropriate ratio for my 35x12-50 tires, and install a new gear carrier.

I know it’s a AMC 20 and it might not be wise to put money into this weak link but I figure it’s worked perfect for 28 years.

So to my question:
I am not going to use an ARB to costly. So I am thinking a Auburn Limited Slip, Detroit/Eton Locker any ideas or advice. Any input would be greatly appreciated.

By the way I use my rig on the road in California so a Posi probably not the best option.

I'm with JeepDaddy... Weld the tubes and one piece axles. If you plan to do some hard core wheeling, get the locker of your choice. I would certainly use Yukon's Grizzly locker (but I'm direct with them, so I get a good deal), over Detroit, or anybody else, for cost savings and equal qulaity of warranty. If you only plan on visiting Starbucks and doing some car camping out of the Jeep, I'd go with a good reliable posi for the street qualities.

I don't think Yukon's Grizzly locker's are available for the 20..
