I have a 2003 ram 1500 i have replaced the radio in it with an JVC radio and I need the dash install kit for it < also I need the antenna adapter for the same thing,
where is a good place to get it, and by good i mean "cheap" or even order this stuff online,
thanks for all the help:

 

Try ebay. I am sure you can find something on there.

 

Metra part no 99-6505 for the kit or 99-6503 both are the same the first one has a pocket instead of just blank ABS up to you.
Antenna adapter is a 40cr10 both parts are from metra.

Harness is a 70-6502
