Exhaust tips - what would look stockish?

[davepl]

I think I'm going to run my exhaust out under the rear bumper, rather than behind the tire was would have been original. I don't usually deviate from stock but this is a pretty easy change to reverse later if I don't like it.

The question is what tips to use! On my Pontiac (same scenario) I used Chevelle tips, as you can see below. Any suggestions on what might look good? And please, not those big Bow-tie ones...something that could pass for stock in 1970 if they had been doing that on trucks.
