Hi folks I'm a Jeeper and own a 1980 AMC CJ-5. Today I was at the dump getting rid of some junk and came across a Dana-Spicer Power Lok . Typical Power Lok with two-piece case and two cross shafts seating in "v" shaped cutouts. Looking at it I think it from an AMC 20. It has 8 ring gear bolt holes (7/16"), The axles splines look about 29 and the diff bearing had no shims (AMC 20's have the shims between the bearing cup and housing). Numbers on the diff are 5 5 66A (probably mfg date), and 23784X (typical Dana Spicer part number endng with an X). Can anyone verify this as being an
AMC 20 Power Lok by the information I have provided?

Not sure about the numbers you listed, but the two i have for amc 20 are 26605 X. They are both from 68/69. My understanding is the X denotes LH threads.

Mopar used a Dana sourced Sure Grip that looked very similar to the AM Twin Grip unit. Could be one of those....

There's nothing on the case that is left hand threaded . The Case bolts are standard 3/8x16 thread.
Another question: What is the AMC 20 ring gear ID (pilot register diameter) where it snugs up on the ring gear flange? Thanks for the replies :)

I have a cross reference that covers over 25 years that converts AMC part numbers to Dana Spicer part numbers, but I don't see that exact number you posted (23784X) anyplace in the conversion chart. I do see Dana #23785X which cross's over to AMC part number 320 5811. The AMC application for 320 5811 is 1967 V8 American, Rebel, Marlin, and Ambassador. Dennis

Thanks Dennis. I appreciate your reply. Been trying to contact some one at Dana Spicer but not getting the right web Site. I guess I'm out of luck. I had a Power Lok in and older CJ-5 with a Dana 44 and it really was a good unit. I changed out the stock Trac Lok in my current 80 CJ-5 for an Auburn and it's an improvement over the Trac Lok any way. Oh well, I found the Power Lok in a scrap yard so no money invested, anyway.
thanks again.
