I don't think you'll know until you receive and test fit it. Honestly, I didn't get the impression it was a total P.O.S., ie., sloppy welds, levers didn't operate, etc. The darn thing just didn't fit is all. Had it fit over the lift arm balls, I'd have been a happy camper for the price.
In case someone still doesn't understand the problem, I've taken a few pics. The Cat 1 lift arm ball width is 1-3/8"...
