There is a couple of pics attached. I used a lowboy ez swivel mount from
http://www.pro-fit-intl.com/EzSwivel.html It tapes with 3M and can be removed from the dash without damage. Since it was a temp/perm installation, I used wiring tubing to run the coax and power under the I/P, through the firewall and to the antenna. I will be mounting other radios and navigation, so needed the room on the dash. It turned out to be a pretty clean installation. Thanks.
