dimensions for an aftermarket radio

i am in the market for a new double din monitor radio and i found this one, http://www.sonicelectronix.com/item_13441_Eclipse+AVN20D.html

problem is i dont know the dimensions and what not to tell if this will fit in my dash...can anyone help me out?

 

the dimensions for that head unit are 7" x 4" x 6.5" and the dimensions for the stock radio in the 03 tacoma are the same(according to ebay sellers, which is all i could find) I would believe its correct and I am pulling my stereo tomorrow so i will check and make sure but it should fit perfectly(key word should) but dont just take my word for it you can do a google search for the dimensions on the stock radio for your taco. The part number for the stock radio is 86120-AD020.

Good luck on installing and you can also check with an audio place just to see if they know anything about it.
