The 10.5's have a pretty good deep dish lip on them. Good luck on trying to find a set, they are very hard to come by. I got lucky and got a set a little while ago. If you can find a full set your prolly gonna spend atleast $1,000 for just the rims in stock finish.
Here's a link where you can pick them up in the chrome finish for a good price:

(They have a silver finish that does not match the stock finish, also I would call and make sure they are a deep dish wheel.
