I'm running the 10.5 replicas from American Muscle for the last year...no complaints...
They match great...only compaint the stock center caps sit a little loose, you just gotta use a little plumbers tape to keep them flush/tight
I have the 10.5 replicas from LP, but I don't have any experience with the American Muscle replicas so I can't give you a comparison. However, I can tell you that the LP wheels are very nice.
I'm pretty sure that both the ones from lethal and american muscle are made by the same company which is wheel replicas. The only other compnay that makes the 10.5" wheels is afs and the afs ones are very expensive.
